No Nicolaitans

I don't have time to respond properly, but a couple of things immediately came to mind when I read your post.
It's obvious that the fault lies with the one harboring bitterness. The "why" doesn't matter (as far as I know). What matters is that the one who is the object of bitterness should continue to be an example of Christ regardless of how others perceive them.
A few verses popped into my head...
1 Peter 2:12
Having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.
Matthew 5:16
Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
Titus 2:7-8
7   In all things shewing thyself a pattern of good works: in doctrine shewing uncorruptness, gravity, sincerity,
8   Sound speech, that cannot be condemned; that he that is of the contrary part may be ashamed, having no evil thing to say of you.
Luke 6:31
And as ye would that men should do to you, do ye also to them likewise.
I know that may not specifically answer your question as to what are some godly responses; however, it's always right and wise to just continue doing what is right and living godly...and to do so in a spirit of love and not condemnation towards others.
 
 

First, I would say that the feelings of guilt, fright, and hating your sins are good signs. I know that might sound strange, but it shows the struggle between your flesh and the new spirit within a saved person.
What is the unpardonable sin? As you've attested, you'll get different answers from different people. Some here may even disagree with me, but let's see what the Bible...what the Lord Jesus Christ says the unpardonable sin is...
Matthew 12:31-32
31   Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
32   And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
 
Now, what is blasphemy against the Holy Ghost? The Lord Jesus Christ tells us in the previous verses...
Matthew 12:22-30
22   Then was brought unto him one possessed with a devil, blind, and dumb: and he healed him, insomuch that the blind and dumb both spake and saw.
23   And all the people were amazed, and said, Is not this the son of David?
24   But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils.
25   And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:
26   And if Satan cast out Satan, he is divided against himself; how shall then his kingdom stand?
27   And if I by Beelzebub cast out devils, by whom do your children cast them out? therefore they shall be your judges.
28   But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you.
29   Or else how can one enter into a strong man's house, and spoil his goods, except he first bind the strong man? and then he will spoil his house.
30   He that is not with me is against me; and he that gathereth not with me scattereth abroad.
 
So, to blaspheme the Holy Ghost; in short, is to attribute his work to Satan...or to deny that his work is his, and attribute it to Satan. They were basically saying that the Holy Spirit was actually Satan, and the Lord Jesus Christ received his power from Satan. That's my understanding of it. How that relates to life today, I'm not sure.
Remember my testimony that I shared with you? I struggled for several years thinking that I couldn't be saved unless I "felt" Jesus come into my heart. It got to the point that I thought that I couldn't be saved at all. So, I know what you're going through to an extent. All that I can tell you is what I told you before...the answers and comfort you need and seek are in God's word. That's where I finally found my answers after years of turmoil because I believed what a man...a preacher told me I should experience...and there wasn't a lick of God's word that supported what he said. There's nothing wrong with seeking advice from others; the Bible even says that it's wise to...just be careful with what others tell you (including me). I can tell you from my own experience, just because a man is a preacher, that doesn't mean he's right about everything. Get advice, and measure it (as best you can) by what the Bible says. The answers are in God's word; you just need to find a way to win this battle that has you not wanting to read it. Hey, you don't have to spend hours in it friend...just try 10-15 minutes a day. You'll get there, and know that I'm praying for you.

I would like to add one last thing...
To any Christians who may be reading this thread and doubts have sprung up in regard to God being the one who causes all things to happen in your life...this would lead one to blame God for any and all troubles that may arise, any heartbreaks that may come, and any sin that may be present. Let me assure you that man has free-will, and while the Bible does teach that God works and moves in the affairs of mankind, God doesn't cause everything to happen that does happen in our lives.
This may not mean much to an unbeliever, but to a Christian...here is biblical proof that man has free-will...
This is God speaking in each instance...
Jeremiah 19:5
They have built also the high places of Baal, to burn their sons with fire for burnt offerings unto Baal, which I commanded not, nor spake it, neither came it into my mind:
Jeremiah 32:35
And they built the high places of Baal, which are in the valley of the son of Hinnom, to cause their sons and their daughters to pass through the fire unto Molech; which I commanded them not, neither came it into my mind, that they should do this abomination, to cause Judah to sin.
Hosea 8:4
They have set up kings, but not by me: they have made princes, and I knew it not: of their silver and their gold have they made them idols, that they may be cut off.
 
Now, before anyone panics and says, "But God is supposed to know everything!" Remember that God communicates with man in a way that man can comprehend and understand. His ways are above our ways, and our finite-human minds can't grasp all there is to know about him. God is holy, righteous, and true...it never entered God's mind to have (or make) them do these things...in other words...it never entered God's mind to be the "causal agent".  They committed the acts all of their own free-will.

I believe the gift of tongues was a spiritual gift (given to the early church) of being able to speak in a foreigner's human language that was otherwise unknown and unlearned by the speaker.
Yes...in addition to the name of the Father and of the Holy Ghost...as Jesus Christ himself instructed and commanded in Matthew 28:19.
No, I believe in one God in three persons...the Father, the Son, and the Holy Spirit.
