I feel stupid

Basically the title; I feel like a stupid teenager. I think what stems from the belief is having an extremely hard time following instructions.

It doesn't matter when I get it in the form of written text, a video game, or a person talking to me.. whenever I recieve instructions, I get very confused. My brain processes it really slowly.

Sometimes, I'll even do the exact opposite what they want and I'll end up embarrassing myself. Like, an annoying ton. It's such a horrible feeling, and I really hate it.

It then gets even more worse when I have to work with people and they're clearly impatient and get secondhand embarrassment because of my basic inability to follow directions.

I really hate it when people start saying mean things, too.

I've got this friend who is clearly impatient whenever I'm slow. We were playing this video game together and they called me stupid and an idiot during times I REALLY wasn't getting the game. I hated how that felt, even though I understood why they were getting frustrated. (this is why i HATE playing video games with people, i don't want to risk making people upset)

I don't know if I FEEL stupid or if I AM stupid. But something about having a hard time following basic directions makes me feel ashamed, and slightly concerned.
