Always Talking To Myself Symptoms Are These Symptoms Of Any Medical Issue?

Are these symptoms of any medical issue? - always talking to myself symptoms

I feel like everyone watched me the whole time, and everyone laughs at me behind my back. I sweat a little when I'm surrounded by people, because I do not like crowds. I am very shy and not talk to people. And I find it very difficult to make friends. I have terrible handwriting, because my hand is still unstable, and I find it very difficult to see sometimes. I can not stop talking to me when I'm alone. Can someone help me. Please do not make fun of me in the comments.
