Hi. I understand your concerns, because till now I didn't tell anyone (except my t and people here) about my problems, not even my parents or my closest friends, because I'm too embarrassed I know in theory I shouldn't be, but I am...
But sometimes I'd like that they knew about it, because they would know and understand me better. At the moment I'm not ready to tell anyone though.
Sometimes I think of it when I think about finding a possible boyfriend...I never really had one now, but if I happen to find someone I feel well with, should I tell him about my problems, and when and how?
I don't know yet...
I know that I'm adding questions instead of giving you answers However, I think that in general it would be a good idea to wait till you feel really comfortable with a person and you trust him/her before telling something so important.
If you want to have people in real life you can surely share this with, what about attending also a real life support group?
Good luck, hope you find good friends
