I'm constantly paranoid about every little thing and I firmly believe my family and friends are getting sick of me
Are you sure that they are noticing your paranoia?
Yes, I guess my friends are getting sick of it
You should ask your friends and family if there is anything you are doing that bothers them. If they say no, you should seek help to see what is making you have these type of issues.
I thought my paranoia would be the reason they get sick of me. I don't think they are telling me I need to stop.
If they are not saying anything about it I would not be too worried. If you still can't shake that feeling though, maybe the best thing to do would be to talk to someone, just to see if they can help you work through those feelings.
