I don't know your friend so I don't know how they would react, but if you wish to share your troubles with them then you should do so.
I have told my friends about my SA and I've also asked them not to get involved for numerous reasons. First, I don't want my problems to be a burden for them. Second, I don't want to ask for their suppport for fear of rejection. One of them has taken my advice and not gotten involved whereas the other one just keeps telling me that there is nothing wrong with me. She can tell because she asks me what is wrong many times when we're out and about but she doesn't want to admit that there is something wrong with me.
