I tried coming out at 18. It didn't go so well. I told my best friend... who then never spoke to me again. It was embarrassing, we were doing the same training scheme and would bump into each other. He completely ignored me.
I was glad when that year was over, I went off to university and never saw him again. I do wonder about him sometimes, and did a little digging. He appears to have completely vanished.
After that, in my first year at uni I had an awful experience and nailed the closet door shut until I was 26.
I had a seizure that was... misunderstood by the people I was with and my own escape was to clam up completely about it for some years.
I did eventually talk to a therapist who gave me a good explanation, it just took some time.
I usually don't talk about my sexuality much, but when I came out to my mother she was just like: "Ok... Anyway, any idea for dinner today?" For my friends I always was 'out', so no issues there. I don't have any contact with my father anymore, so no idea how he would react. Last I heard is he did vote for some right wing party though, so probably not that well.
