When I was your age, yes often. So bad in fact that by my mid twenties I'd given myself a hiatal hernia and a duodenal ulcer. (Translation -- both ends of my stomach tore a bit.)
In my mid twenties I made the somewhat crazy decision to enlist in the Navy. I washed out of boot camp after threatening suicide, but oddly had an experience afterward that I was never able to fully explain to anyone. I'd taken a job working technical support for Hewlett Packard and it was kind of a cushy corporate contract that had been over-staffed because it was new and it was also going into the holiday season, so there weren't a lot of calls anyway. We had a lot of time between calls and I just started writing. Philosophy actually and it turns out that much of what I wrote was very similar to Plato's allegory of the cave from the Republic (which I hadn't read yet). After about a week of writing, I was no longer having anxiety attacks, which I'd had for many years and was no longer physically ill from social anxiety. It was like the opposite of "post traumatic stress", but the psychological industry doesn't have a name for it. I called it an epiphany for lack of a better word.
I really wish that I could give that experience to other people. You sound like you could really use it. I tried for a while, but now I just don't think it's possible.
(Don't ask me how I got past the induction. Somehow I managed to convince them that I was healthy enough. Physically that was true, but I really didn't have the emotional faculty at the time to be there.)
