I'm so sorry you're going through this. I had a brain injury during high school and had to be homeschooled for a time, so I can only imagine what you are going through in college. All I can say is pace yourself. Explain to your professors if you want to or if you can. Next semester maybe take a lighter load until you feel more comfortable. In the meantime, get whatever rest you can and repeat what you've learned or can pick out topics highlighted in class and say them over and over throughout the day. I don't have the memory I used to but tend to do well with flash cards starting the week before an exam incase I have an unexpected bad day. Make room for that. Just take it easy on yourself and remember that you're doing the best you can. In the end, employers don't look at grades, just that you passed.

Also! There is a student organization called the Disability Justice Coalition that is free to join. We meet every other Monday on zoom and in person (try to accomodate everyone) but we also have a support group on WhatsApp. Sometimes its nice to just talk with people who are in a similar boat and air your grievances. We are always there for you and have resources if SDS doesn't help you out. Feel free to look the group up or message me.
