I think I'd like to know more about the OP's actual issue. Is it that you become anxious because you can't think of things to say? Or is it that you are anxious and this makes it difficult to socialize? Either way, there are lots of drugs that could help. If you need something every once in a while I think the Adderall you're using would be fine if that's what works. If you need something more frequently or everyday I'd suggest an anti-depressant, an SSRI or SNRI, in addition to Xanax 0.5 mg or Ativan 1 mg (or Adderall depending on the anti-depressant) as needed. If you feel you need a benzo everyday, which I doubt you do, low dose Klonopin would work nicely. Anti-depressants get a lot of hate, but they can be very helpful with anxiety.
