Anxiety about the future

I hope it's the appropriate space to vent a bit
Last week I did terribly on my mid terms exam, and it's been worrying me since, because I can't afford to fail this course.
I need to work hard on my next assignment that's due in 2 weeks, on top of that, I'm moving to a new apartment next week with my cats. It's going to be a lot of work.
I'm feeding some semi-feral cat friends outside, and I haven't seen one of them in a while, so more worries.
My mental and physical health have been worsening, but I'm still trying (I even went to counselling today for what it's worth, and I quit my most used social media app).
I'm frustrated at myself for being so painfully slow and getting tired so quickly. I have a backlog of to-dos that I'm tired of looking at.
I hope I can pull through until next month. It's 2AM but I can't sleep because I already slept most of yesterday away. Sigh
