Welcome weskerbouts!
Sorry to hear about the way this was handled. Many here have gone through this "freaking out" stage to a more calm and rational place. Actually though I think you are handling matters more calmly and rationally at this trying point than many of us may have at the time.
You have your miracle - a major (albeit painful) event that is setting you free from religion/ists!
And its great that the bad experience has not turned you away from God, faith, spirituality or the gospel ("good news")!
The fact is you have been disfellowshipped because you have a conscience, and they are ignorant and blind to how they should have responded and helped. This is no way to treat someone who is addicted and wants help! But it is a great way to open your eyes to some unpleasant truths and realities about religion/ists.
In time you may be delighted to discover that "the truth" is a person (John 14:6) who absolutely delights in helping us out with our addictions! He is observing closely your journey out of religion and would be delighted should you choose him over religion.
I was addicted to religion (the Watchtower's version) and it's definitely worse than pornography, since one is actively worshipping the "god of religion" and snubbing the "God of Abraham". How on earth can one beat any addiction like that?
I would highly recommend seeing a good Psychologist and coming to grips with CBT (Cognitive Behaviour Therapy). This is part of the secret to unravelling addiction (of any description). Our (addictive or aberrant) behaviour is underpinned by (addictive or aberrant) emotions and feelings, which are underpinned by (addictive or aberrant) thinking, which is underpinned by (addictive or aberrant) beliefs, which in turn is underpinned by a low SQ (Spiritual Quotient). Religion is not the answer! It is often the problem! Just read Matthew 23!
(CBT stops at beliefs and does not yet consider spirituality).
Oh and by the way religion is really anti-sex, whereas Jesus is pro-sex and anti-religion!
Fear, shame, guilt and embarrassment are not of God, they are from the enemy. Jesus loves setting us free from these demonic strongholds employed by religionists, so that we can journey with him whilst we are transformed from within, something supremacist window dressing religion can never accomplish.
Ray Franz' books are a MUST read! They are rather big and represent a journey in itself! He was the real deal mind you! For a summary of his book "In search of Christian freedom" you may want to read the Awake article condemning "legalism" and promoting its opposite. This brilliant article was most likely written by Ray (g79 6/8 pp. 27-28).
Since we humans may give conflicting or erroneous advice it is always best to go to the source - God himself - and on his generous terms namely those outlined in the generous, full and unabridged gospel message (the real "good news") as partly and powerfully described in Romans 3 and 4 where a right standing with God is IMPUTED to believers as an UNMERITED free gift, despite us still being sinners and making mistakes!!!
