I don’t know what to do anymore

I’m in 3rd year of uni (my course is 4 years +2 extra years if you need them). I have extreme time blindness and I can’t manage my time properly. All 4 months of the semester I couldn’t put studying in my routine even though I tried couple of times. It’s not that I’m living the “c0llege life” partying and all that. Not even close. I was extremely depressed the 1st year. I wasn’t going out for months. I probably still have it but I can’t afford a therapist right now because I’ll start some extra lessons for the classes that are the most difficult for me after my exams. Now is my exam season and I’m doing very bad again. At the beginning of my exams I was so motivated and I was studying every day I even put on my walls motivational quotes and shit. After my second exam that didn’t went as I thought it would go I was sooo disappointed with myself and now I can’t get myself to study because I’m sure I’ll fail either way so I gave up. I know that I can’t study days before the exam and that I need more time to understand and memorise things but still it seems like I can’t bring myself to study and keep up with uni. All I do now is rotting in bed and distracting myself. If I don’t I’ll think of all the time I wasted for once again and all the “I could do that”, “I shouldn’t do that” and feeling like I’m going crazy with all the thoughts and the self downgrading. Now it’s 5:37am, I can’t sleep and there’s much more I want to say but I’ll end it here. Anything that’s going to help me get out of this (uni wise, psychological wise and anything wise lol) is acceptable and much appreciated. Thanks for reading.
