oh, yeah, all those voices in my head. A friend of mine cured me of this by saying two things over and over til I got it.
"What other people think of you is none of your business!"
and
"Stop letting them live rent-free in your head!"
PS, I used to be shy and now you can't shut me up!!! The Effexor will help. Make sure to try a higher dose before giving up on it. I take almost 300 mg a day after a very slow very long time increasing it.
