I’m breaking down

I’m an Engineering undergrad student and I don’t f*cking know what’ happening. Everything is so overwhelming, and everything keeps stacking up. I genuinely don’t know what to do anymore. I want to keep studying but anything I do keeps on backfiring. I have a brunt of my finals in a week or two and I don’t have any confidence on passing any of them. I’ve already spent so much money, and my mental health has been deteriorating. I don’t know what to do, what can I even do now to get back? Any help or questions would be much appreciated. It all just feels like shit, and I don’t think I’m doing enough, I don’t know how to do anything.
