How to function at school

I have a question for other autistic people...

How do you manage to commit to school/education/jobs? I'm currently in college and I'm thinking of unenrolling because of my bad attendance but I really don't want to.

I enjoy the subject I'm doing but with the added pressure of assignment deadlines, grades, my perfectionism, peer acceptance and sensory issues, I really do lack the motivation to maintain a good attendance. I'm only meant to go into college for 3 days a week but it feels like it's way too much for me. 

I have a key worker who has helped me by clearing up with my teachers why I miss college so I don't get booted off the course. We've also done some work on time tabling so that I might not feel overwhelmed with my work load and other methods like taking breaks during class times. I think these methods have kept me going to be able to reach this point of the year but sometimes especially during/after burnout I revert to not using these techniques and I feel that sets me back. 

I want to go university but I don't think I'll be able to go if I keep on going like this.
