I'm sorry you are feeling like this. School is realy hard (you know it ). I'm sorry it's overwhelming you.
I know more a less what it feels like, pushing your self to get up in the morning, to go to classes, to study...aghrrrr. It can be realy hard! But I still do it, hopping for better days and hopping for a future.
Well I did take a break, but for me it was a "life or dead" situation. I felt very badly at that time. It was just a resting time, indeed I did almost nothing in those weeks...almost all the time in bed. But after that I know I have to keep going. Sometimes I wish I could quit, but when I think about it and imagine the scenarious I would be in, they wouldn't be very good ones.
I start my medication in those weeks, so now I'm waiting for them to make me move. It seems like your treatments aren't enough to make you feel better! Maybe, and I'm far away from being an expert, maybe you can have them changed.
Taking a break is great when you feel much pressure and stress in your life, because that can make depression worst. When I stopped for a few weeks nobody understod me and some of my family members said to me that I would regret it later, but until know I don't regret it, and I think I won't, I would barry myself alive if I kept trying at that time. But in this steady state I am now, where I basicaly do my best to study and avoid to be consumed by stress I don't think that take a break would be a good thing to do. I don't do many things, but still I have a porpuse in life. If I was at home with my parents I would probably sit in the sofa the all day and that is not certainly a life.
What I think is that I have to fight, even I get late to classes everyday in the morning, even I study less than everybody else and don't have time to do much more. I have to. If I want to live, there isn't another choice. But if a break down like that catch me again, I would stop my school for a while again. In this moment it would not make me feel better or improve my depression.
I hope you get better days!
