Is it possible to go to a Uni near you and ask about your situation and what you can do to possibly enroll in their school? Alternatively, a lot of programmers and CS professionals are self-taught. Maybe that is a route that you can take.
I enrolled in a two-year general education / liberal arts/ transfer degree. My school had articulation agreements with some of the Universities in the area. So by completing the degree, if I transferred to one of those schools, I would have already completely all of the writing, history, communication, humanity, art, etc. courses that had nothing to do with an actual degree but are required for a 4-year degree.
At the time, I knew that I wanted to study some kind of science but I did not know which field. Since math is involved in all of those fields, I took a Calculus 1 & 2, Multivariable Calc, Linear Algebra, Differential Equations, and Statistics. I tried a Physics course and hated it. I had a similar experience with Chemistry. Then I took a programming course and fell in love with it. Then I took another one. I then transferred to a 4-year Uni and got a Mathematics degree with a focus in computer applications .
When I struggled with certain concept in math I simply watched youtube videos for help. Some of those videos were from "The Organic Chemistry Tutor", "PatrickJMT", and "Khan Academy". You can find instructional videos like that for just about any subject. There are ones for Computer Science and programming, too.
I used Chegg.com sometimes but it costs like $15.95 a month before tax. They have textbook solutions for a lot of textbooks but some of their answers are flat out wrong. So, it can be dangerous to use them for help. I didn't use these textbook solutions to cheat but to help me understand what I was doing wrong. It was kind of like reverse engineering and I learned a lot from it. It also helped me analyze code because the thinking process is very similar - it's just a logical flow of content.
This is a good place to take an introductory programming course for free, https://www.coursera.org/learn/python
Maybe checkout r/cscareerquestions and ask for free sources to study from to get a sense of computer technologies / languages / theory so you can get a feel for the material.
Also, Computer Science and Math is really difficult! At least is was for me. I had to spend a ton of time studying it and pretty much gave up a social life. But it kept me from doing drugs and drinking. Now I have no interest in doing either.
I should also add that I have a friend with schizophrenia and he is doing Android development using Kotlin, I believe. He got his degree in Cyber Security.
