29M, disabled...going back to college soon. Afraid I won't do well.

I'm 29M, and I'm going back to college starting next week. It's online, and it should be paid for because of federal and state grants. I have 45 credits transferring in, and only need about 18 credits to earn my associates degree in computer information systems.

I graduated high school in 2015, with good grades. But, I had severe anxiety and depression, bipolar disorder, etc...dropped out numerous times, this is my latest stab at finishing my associates degree, then either getting computer certifications, or finishing my computer science bachelor's I started over a decade ago.

I haven't had a job in 3 years...I've just been living off of social security disability and food stamps in a small apartment.

I'm just afraid that I still won't do well...I tend to procrastinate, a lot, but I love learning...math, physics, computer science, philosophy, etc.

I wish I could just sit and do the work I want to do. But I can't concentrate. And so I just doomscroll subjects I enjoy on YouTube. I can't sit and read like I used to. Also, I'm almost 30. I've barely accomplished anything since graduating high school.

Just...I know I'm at least making progress...but I'm afraid I'll trip up again.
