Constant sadness

Hello everyone and thank you for taking your time and reading this post.
Well, this "constant sadness" thing has been going on for approimately 6 months now and I'll quickly try to explain what's going on.
Due to extreme stress and a giant load of studying in school (more than 5 hours daily for about 10 months, no rest, not a single day), my brain just kind of "blocked out" especially at the end. I found myself (and still am) unable to think clearly, literally unable to try and think of something...and this has led me to the state of sadness. I've been feeling sadder every day since I am obssesed with the fact that I am becoming dumb and every time someone says something or when I read any quotes, my mind immediately warns me that I won't understand it and I panic before I even start. That's why I'm constantly sad, I have a very low self-esteem and I cry multiple times a day, realizing that I simply can't think about something without flashing and blocking out. I am not sure either I am falling into depression or am already in it, but I just walk around all day with a sad look on my face and with rather quick temper. I only have about one month of holidays left, then the school starts again...does anyone have an idea of how to make it stop, how to start thinking clearly and finally, how to avoid or get out of this depression that is ruling my mind and that seems to have no end...
Thank you very much for all your answers.

I would see a therapist to see if talking helps. Usually they have strategies they teach you to minimize depression. If that's not available I would try medicine although it has unfortunately never helped me much. Sometimes if I feel bad enough I take longer time off from school so I don't mess up and get enough time to recollect myself.

You constant sadness, me constant sorrow, therapy helps and so does medication. I hope it does for you to.

Take it one day at a time that's what I do. I wish you the best of luck and virtual hugs I'm here if you need to chat
