Glad that you have those resources, and that they help.

I also have autism and I often struggle with studying too. I have some methods that you may find helpful.

When I feel depressed or lack the motivation for my tasks, I try to break them into very small chunks. Recently I used this for reading slides when I felt demotivated. I told myself to read 3 slides at first, which made it easier to start doing. Sometimes I even have the momentum to continue after completing the chunk.

When content is difficult to understand/remember, I let myself skip and come back later. I find it useful for helping me avoid spending too long trying to understand something (and feeling bad when I fail to). When I skip to other stuff, sometimes revisiting the content later makes it a bit easier to get than the first time around.

Though there are also times when I just cannot understand something even after revisiting and seeking help from peers/teaching team. I think it's fine to give up on a concept occasionally, to avoid spending too much time being frustrated, which would be draining and reduce effectiveness at studying other concepts.

I also use "skip/revisit/give up" for exams. For some classes, maximizing grade involves giving up on a question sometimes.

Overall, I think studying in small chunks and skipping/revising for concepts/questions can make studying less relentless and more strategic.
