You're an old member on this site and just recently realized that you have a social anxiety problem?
But yeah... join the club. Hopefully for you it doesn't snowball into other mental disorders like it has for me... chronic depression, generalized anxiety disorder, avoidant personality disorder, etc (plus I've got ADHD-I). I understand way too well the hopelessness and helplessness that result from the realization that you are going to be struggling with this **** for the rest of your life... and that you'll probably never be truly "normal: in that sense.
Try not to let it get you depressed though, there are still treatments available that can really improve your problems, even if they don't necessarily cure them. Many people are born with all sorts of different obstacles, and the best you can do is play the hand you're dealt to the best of your abilities. Coming from somebody who deals with so many mental issues every single day (even apparently considered to be the most serious mood/anxiety disorders outpatient at the local hospital's mental health clinic), I realize just how pervasive and unrelenting they can be. Essentially, you ARE your mind, and you never get a break from it, nor can you ever really escape from it.
Unfortunately, despite all the miracle advances being made in other fields of medicine, psychiatry, by the sheer complexity of what they're dealing with, don't have the same level of refinement regarding treatment options or even diagnostic features. The diagnosis isn't based on anything physical - it's based on a patient's self-reported history and if you grow up like I did from a relatively young kid with all these mental disorders, it's hard enough to communicate my problems as a lot of the time I just happen to assume it's normal behavior.
As far as the drinking goes, that shouldn't be a problem at all. I don't know quite how old you are, but unless you're being pressured to keep up with your friends/peers, just ignore tham and drink less when you're on klonopin... it's very dangerous to go overboard.
