I don't want help due to ego

I need help in studying. Even if I do ask for help it's hard for me to concentrate since at that moment I am angry at the fact that I need help. Regardless, it's been hard for me to listen and concentrate. And no, I don't need Ritalin, I'm not diagnosed with ADHD. I have anger inside. Call it depression or whatever, I don't care. I'm not gonna label.
So that's the deal. I am angry and disappointed I can't do everything right. And I can't follow other people's instructions, whether it be teachers or some people attempting to help me.

I don't know what am I gonna do. How am I going to get rid of the anger so I'll be more calm? I'm thinking it might help...

There might be something you're repressing?? Like, for example, some people find it difficult to sleep because there's something on their mind. I know you're angry because you're struggling to study but this could be the same thing as struggling to sleep due to an underlying problem, perhaps?

You say you don't want help because of your ego. To anyone else, I would suggest opening up in depth to someone about all the things making you angry and they might be able to help you process these thoughts. Sometimes, offloading to someone helps. They don't need to 'help', necessarily, unless you'd like them to - it'll be similar to documenting your thoughts in a diary. If not this, then I'd recommend therapy however your title says you don't want help due to your ego.

I slept a little more and feel better.

A goods nights sleep or nap is always a good place to start

I got up today and felt better, but became angry when I sat near someone I despise because he'd make fun of me. That anger has remained in me ever since...
