I Am Sorry If Im Not A Good Friend

A friend of mine from college is under a lot of stress. Lecturers are pressing him far more than they should, and his friends are putting pressure on him to do stuff outside of college when he keeps up with the work etc.
On top of that he's got adhd and autism to battle as well the fact he was diagnosed with clinical depression a few weeks ago too. I don't know what to do when he talks about his issues though. The best I can do is listen. I've talked to his friends and asked them to be more lenient with him but they didn't listen
