This is criminal! I sometimes wonder why its so easy for some JWs to use fear of destruction as such a weapon. This is emotional blackmail. Your uncle has some 'splaining of his own to due come any sort of judgement day.
In the meantime, remember to breathe and live with your head held high. You are a worthy blessed individual. I'm sorry for all the stuff you are going through right now. You can pm me or any of the other gays here or for that matter most of the straight folks if you need support.
Good luck,
Gretchen
