University isn't very good at providing positive feedback, it specializes in negative stimuli. Or no feedback at all, your imagination goes wild and you will start doubting yourself and exaggerating the challenge. The less contact you have with the staff, the more inhuman and worse it gets.
You might feel overwhelmed with the amount of material, especially if you skip lectures, or the lectures make absolutely no sense to you. The bare minimum is to understand them, you might need to actually open a book in that case.
You need to make it your goal in life, right now your goal might be more "go home, feel good" or pursuing some artistic pipe-dream. I'm not saying to get rid of those things completely, it's just your study needs to be at least on the same level of hierarchy.

No wonder you start doubting yourself, most people do. Seek therapy, however drugs (even prescription) are just a short term solution. By the virtue of the placebo effect alone, they will help you regain control. But once you have control, you actually have to do the work yourself. You will fuck up though, again and again - this is the sad, inescapable fate of all humans.
