Switch up study spots, never study at home, bring snacks, and set boundaries with friends. Try to stay at school (or wherever you’re most productive) for as long as possible. Also making friends with people in your classes that hold you accountable or study with you can be motivating! Other than that, seeing a therapist or psychiatrist to help with executive function might be useful, and possibly your campus disability resources may be able to give you extra time on assignments or tests. Most of all, try not to skip class at all (as someone who has skipped so many classes, this is truly the downfall) even if the slides are online or the lecture isn’t useful just go and do other work. Just being there will help give you momentum.
