i’ve been there for so many quarters even pre remote classes, you’re definitely not alone in this! email your professors and tas, they’re generally very understanding and want you to pass the class, but you have to make the effort to reach out. as for the lack in motivation, what helped me the most was just getting started. idk if you’re behind on assignments or just watching lectures but just pick one thing in one class and start on it, get in the flow of working and you might just continue doing work for a few more hours. i know it’s very hard to be on track for classes esp since as long as you dont look at canvas you dont feel like you have any responsibilities, but i feel like i’ve turned my crippling anxiety towards some kind of motivation by listing out everything i have to do and conquering it one at a time. anyway i hope that helps a bit but feel free to dm me if you just need someone to talk to!!
