When socializing with people at times I get so anxious that I stutter and my mind goes blank like I tripped a circuit in my brain and my words can't come out and I can't find the words to express what I am trying to say , l feel like I can't control my tongue. its so embarrassing, then my hands shake and I feel disoriented and my tongue feels numb. Then I have a fear that is so bad I can't think. I have always been like this but it seems to be getting worse. I take antidepressant medication . but I feel I need something to help me stay calm when this fear comes over me.
