I barely studied and my tests are tomorrow

Usually I'd be so stressed about it and prioritize on my studies but I genuinely can't do shit rn. I always find myself regressing after periods of taking everything to literally or seriously. Its gone so worse that I can't even write properly in paper. The difference is especially clear in my hand writing, how I can go to either clean, fancy semi cursive to a fucking 5 year old's hand writing. But to be honest, while I did try to force myself to get back into my regular strict mindset— I still couldn't do it. As of now, it's about to strike midnight and I've only done 5% of reviewing on 2 subjects out of 11. I'm wasting my precious time of reviewing to find some sort of relief, which is writing about my fogginess. Even though I'm at this kind of "regressing stage" I still do feel extremely anxious about my studies, I just can't seem to do anything even if I try to find a solution. I'm practically trapped in my own fears of failure by feeding more of it with worries and "relief stimulation".
