Whenever I talk to people (especially at work) my mind just goes blank.  I’ll know what I want to say but as soon as I open my mouth, I get nervous and I draw a blank.  Now, it’s not like I just don’t say anything… but it all comes out kind of jumbled, not very precise, and a lot of “uhmms”s.  Afterwards, I’ll play the conversation over in my head, and instantly think: “why didn’t I just say” this, or “I should’ve said” that.  Basically, I know what I want to say but it almost always comes out poorly.  It’s as if my thoughts go through an anxiety filter before they come out.  It’s just so frustrating because it makes me sound kind of stupid, at least that’s how I feel.  It’s very frustrating.
