Hi! First of all English isn't my first language so excuse my mistakes please.

I've always been a very good student until high-school. I always had the best grades, and had no problem getting them even if I didn't study a lot for it. People were saying I was "gifted " but obviously it wasn't the case. 

After graduating from hs last year, I was admitted to medical school, which is very prestigious in my country. 

The problem was, and still is, that I became depressed and I just cannot concentrate on my studies. I feel very detached and my brain don't seem to understand that this is very important for my life and futur and refuse to cooperate. Getting up to sit at my desk and just read a document became extremely difficult for me.

That resulted in me failing last year so now I have one last chance to redo first year and I don't wanna fuck up this time.

Can you give me some advices please?
