I over think every little thing, is this normal?
I am a Junior in high school and I seem to fixate on every little thing . Like if I say something stupid to someone or something like that it will piss me off and I will fixate on it for the rest of the day. Little things that don't even matter will literally linger in my mind the rest day and its like I can't even stop it. I understand and realize that those things don't matter at all but if a little thing happens during the day like a social issue or even just giving someone a bad handshake it will stay/linger in my mind the rest of the day like a bug in my brain. I just wanted to know if this is normal or if it's some kind of mental disorder or something like that. Please help me out with any advice or comments you can give me. Thanks.
