How is everyone so good at this?

Im 20 years old and I'm mildly dyslexic. Most of my grades are C, C+, C- and I'm squeeking through in the hopes that I can somehow manage to get a degree in Computer Science. I read very slowly. I don't retain information and have to reread the same passage multiple times. I'm on the spectrum, I have ADHD. I'm excited to learn but I just can't. I struggle to listen and give out instructions. I can't make friends. I'm underweight. I'm losing my hair. I have anxiety attacks everyday and I've had a panic attack almost everyday for the last 4 months. I'm living in my parents basement. I have very low self-esteem and I feel so alone. How do you all do this? How do you cope with this shit? No one seems to understand. If I try to explain this to people they all get mad at me for not working hard enough.
