I'm fine, but not really. Last year after quite a painful breakup, after which everything went to shit. Soon after being dumped I was pushed out of my own startup by my co-founders. This lead to me to a self destructive spiral damaging everything I touched, especially uni, which in reality is my only true responsibility. (I'm very lucky to have come from a stable and supportive environment) This (academic) year was me basically trying to fix everything I fucked up last year. Passing all the courses I failed while listening to quite a few new ones. I did fine and there are just fivee courses between me and my degree. In 5 days I have a final for one of them which I MUST pass now. If I fail, I probably won't be allowed to re-enroll, which means I won't be able to get my degree, which means the last four years have been for nothing. The worst thing is, this is my fourth year in a three year degree, and if all goes well I'll only be able to finish it next year. So five years total. To top things off I failed this exam last week by a big margin 20%. I spent a month and a half studying for it, now I have less than a week to reprepare. I don't know where to start or what to do. What I did wrong last time. I lack motivation and it all feels pointless and useless. How can I do something in less than 5 days, that I didn't manage in more than a month. I'm not sure if I'm too dumb to pass, or just an idiot for not being able to force myself to sit down and work, to give 100%. Sorry for the rant, thank you for letting me get this of my chest. I'm probably gonna go to bed now, wake up at four and try to get some work done.
