there's stuff I have told therapists which I have never told anyone else. There's stuff I would tell them that I no longer talk about with friends/acquaintances. I can't imagine very many friends would WANT to listen to a timeline of my troubles.
It's not like what you see on TV or movies, just like lawyers in a courtroom aren't like what you see on TV. (I've seen the real stuff quite a few times thanks to my previous jobs.)
I would suggest at least trying a counselor a couple of times. You might even have some friends who could recommend someone. The health insurance I used to have actually grouped counselors by their specialties, as in types of problems -- survivors of sexual abuse, anxiety, divorce, etc. That was pretty helpful.
