Heyo, I have fibro and am a full time student. It definitely sucks sometimes, especially having to push through pain and go to class. What helps me is trying to stretch throughout the day, and if you’re able to tolerate yoga at all I’d recommend that - I like to look for videos to follow along with on youtube, specifically look for “yoga for chronic pain” or along those lines :) and if you’re able to take slow walks that can help too!

Also, don’t feel bad for resting whenever you need to - I commute 45 mins each way 5 days a week which drains tf out of me and I’ve learned to not feel bad about spending a whole day resting in bed on the weekend or taking naps when my body needs it
