I feel that i am the stupidest human being in the world

I know humans make mistakes but I make more then you can imagine. I'm socially retarded and struggle to even say a few words to anybody. I do stupid things even when I think it through. I ram into things randomly. The worst of all is the stupidity. Everyday somehow I manage to do something stupid everyday. I try to think it over and in my mind it seems ok untim I hear everybody else's opinions, thinking I'm an idiot

People don't even see me do half the stupid things I do. I forget the simplest of things.

One time I had to write a speech that appealed to teens. I wrote on alchohol and how it BENEFITS YOU. When I presented everybody laughed and the teacher thought I was
retarded. I didn't realize how stupid it was until a week. A WEEK!!!!!!!

Another time was when I was texting a girl. I said that a song reminded me of her. Her response was a weird fraise. My response was "?" Right when the text sent I realized it was a song and she sent me back random giberish. I didn't even bother texting back and gave up. I never have a chance with her now...
I can't go on like this much longer. My mother experiences the same problems but are a worse then mine.

Is it some disease or disorder? Do I need help?
