I understand totally, I think it is only natural that we push people away who we are afraid wont accept us, of course they dont understand this being Unaware of our problems leading to alienation of those around us.
I do wish that when coming out it would magically fix poor relationships that could possibly have been fine had we just been out to begin with. It doesnt seem to work that way though.
I also regret.not.trying to do things much earlier, and I regret taking as long as I have to get where i am, but i think most of us have those regrets.
In any case good luck, I think you will do just fine I have watched your confidence increase over time and I have faith in you.
