Hey Trapped and welcome. Yes another one here.
Here's my story up to the beginning of my fade, if it's of interest/help (it's a bit long but it helped me no end to get it all out there!). The only update being that I haven't been to the meetings for a year.
To answer your questions:
(1) It was a nightmare towards the end from an emotional health perspective. I only found happiness once I left and became authentic - not just talking about my sexuality here, but just about my beliefs in general - e.g.shunning.
(2) I built up my friendships outside of the congregation and made a transition. Gradually spending more and more time with my "worldly" friends. I have been very lucky, I think, and I have never been short of support from my non-JW friends. I also have very good historical friends both straight and gay who have are ex-JW (my best friend is gay and faded before I did, though he is still mentally in unfortunately) and I also connected with an ex-JW LGBT support group - all lovely people. Let me know if you need any more information. I know it's not easy so let me know if you need any more information.
Sending big hugs your way
