Is it normal to not understand how others see you and are paranoid?

Stop caring what they think. And accept whatever compliment you get. Nobody is plotting to screw you over. Try to think about people more positively.

same. I just figure everyone hates me (or they would, if they actually cared that much)

I feel exactlyy the same way

I know exactly how you feel..

I grew up poor and the smell of heavy cigarette smoke on me with crooked teeth with a single mom. got made fun of and no friends until 8th grade I had 2? anyway my point is..I didn't let it get me down As I grew up I said and did what I wanted didn't care what anyone thought of me still don't well to a point..I wasn't wild But I was different. The only one in small town that bought those orange overalls.wore them and lovedit regardless of the fingers pointed at me. the old musty long sleeve short dress and the fabric a little heavy and brown.from my Grandmas closet I liked it wore.in Hugh school.Yep got made fun of.But didn't care.Enjoy life don't worry what people think. It all comes down to you and how you see yourself. Be a good person do the right thing and be Happy.

I wish you wouldn't care so much about what other people think of you, their opinions are pretty unimportant. Don't go into conversations thinking that someone automatically dislikes you!

You seem poor at determining body language. Body language signals can be less "clear cut" than verbal signals to some people. Because the signals aren't exactly to-the-point (as compared to an "I like you" statement), your stronger, clearer insecurities override the meeker body-language inputs you receive and interpret them into something they are not.

I feel as if I am rambling. Take care! I think you do have a clue, but do not feel confident enough to "roll with it"

You seem like you would be great as physics ;)
