If you are about to fail a class or out of school due to anxiety, go and tell someone.
This happens all the time so there will be standard things they can do about it, routines, process and guidelines etc.
When stressed things can seem epic and scary, which makes it hard to reach out.

This sounds like ADHD to me. It might be partially anxiety, depression and other things mixed in. It's hard to tell as they can cause and worsen each other.
Try all the standard advice for stress and procrastination and see what works for you. Do you have a sporty hobby, try doing more of that. Is your diet or sleep schedule crap, sort that out. Read about the physical impacts of stress so you can recognize the feeling and find some method that works to chill you out, whether that's meditation or going for a walk or reading a book. Find stupid tricks that work for your brain (study buddies, pomodoro timers, breaking things down into smaller tasks, starting the task while intentionally not caring if it's perfect or even good just to get going, there's lots of different tricks that work for different people at different times).
