I also did a lot of reading the summer before I went back to school. I think that that helped me quite a bit. I was pretty much recovered when I went back to school, so it was not that difficult. However, I still needed quite a bit of sleep and I had to study quite a bit. Because of my illness, I believe that I had to study more than my schoolmates to get the same grade.
Time is also a big factor.
It took me four years to recover before I went back to school. Saskia, I hope that you are doing well now, and please remember to always stay on your antipsychotic medications.
