Hi european333, and welcome to IPS. Unfortunately, this sounds like an intrapersonal problem, and not an IPS. Working on yourself with the help of professional or internet ressources might be a good start. But as it stands, I'm voting to close this question as off-topic. — OldPadawan 22 secs ago

The OP seems to want general advice on a general problem. They provide a specific example of being called a "dumbass" at school, though if they were a tad more bold, they might even provide the resistance that they have to asking questions on SE as an example. I mean, seriously, their profile starts off with "ATTENTION MODERATORS! I have some big issues that I need help with. Keep reading!"; it's precisely this trouble, and their difficulty responding to it, that they're trying to ask about. — Nat 1 min ago

Sidenote: IQ is questionable as a measure of intelligence. If you yourself feel that you are "a little slow to comprehend something", that's one thing, but it doesn't necessarily correlate to IQ in any way. Ultimately, any answer to how you should respond to this bullying will probably not be dependent on your IQ. — V2Blast 9 secs ago
