get over my social anxiety

I freeze. My heart is going a mile a minute, my temperature rises, my body stiffens, I get nauseous and shake uncontrollably. My mind goes blank and I try to think of anything to say. but when I do say something, I see they’re judging me. They probably think I’m emo because I always have a blank face on. It’s hard for me to get out of the house because I’m so scared of people. My social skills are horrible and I’m no fun to be around what-so-ever. =[ I really want to fix this all and not be so insecure. I’m not sure how to get over it, but it’s a work in progress…
