My social anxiety has actually gotten better with time. I remember at the beginning of the semester in one class, the professor had us go around and say our names. I was freaking out, palms sweating etc, until they got to me...and I said "Dan", and after that...it was done with.
Social anxiety is a bitch, there are drugs that are perscribed to treat it that have a less chance of abuse/addiction than benzos (Paxil, even Lexapro), but the withdrawals from these can sometimes be uncomfortable. Although, the withdrawals/side effects from benzodiazepines can be albeit fucking hell.
