Yo guys, I'm a 18yo French student that is drunk af,it's my story.

So I've started weed few years ago (3 I think) and I stopped for a nice girl that ill name Rose. I also started to workout. I loved her, my first love and when has come the time to go in high-school she went to an another city at 3 and half hours of drive of my new city... 
U see that coming, I went at her home for several days before the school start and the day I came back at home she broke up with me by message. At first I don't cry or something but time passed. She broke up with me 4 month ago. 
I entered a biology school and I don't success well at the courses. I'm funking bad at chemistry and some shit I used to like before I started this school. My mental health is down, I'm starting again to smoke (not weed for now) and drinking alone. 
I never had many friends but what I had were the best. My best friend had to move out of France to go live in Martinique (idk the name in English). At the time, 2 years ago it also took me down. Now I just have like 2 or 3 real friends left and the new ones iv made in my high school are not how I expected real friends.

Summary: still thinking about my ex girlfriend, lost in the new courses, new friends are not what I imagine real friends, I can't tell my old friends all the shit I'm going through. I need an emotional support from a girl but can't find it, neither from my family or than friends I used to had or the new ones. Funking lost bois, that's why it's my first reddit publication.

My text was confusing I know but alcohol talk for me and my bad English too.
