I don't know where else to go

Hello! Please someone help me figure out what to do I am in the process of ruining my life. I am now 20 years old, I live in Morocco, I had Bac with mention très bien three years ago, before that I was always top of my class, I got the highest marks in my city and in my region in sole grades -not even exaggerating I have trophies- ..and ended up in lafac fst (I never knew about it before), up untill that time I was a motivated talented hard working kid, after that I have been in the same two years of deust for 4years, even tho I have always loved the biology studies that I'm in now, but I just can't bring myself to put anymore effort into anything. I have always dreamt of being a teacher and I am very passionate about languages, this year miraculously I got the job of my dreams as a kindergarten English teacher, that along with my -hopefully- last year of college seemed manageable. But now I am halfway through the year and I couldn't care less if I get fired tmr and expelled from college. Even tho I am in a really poor family and have nothing to count on when I grow up but I just feel how meaningless it is to do anything I honestly couldn't bring myself to study for a final I have tmr no matter how hard I try. I know that there is no way out other than study hard and work hard untill I get through this phase because it's gonna pass one way or another. I honestly don't know why I wrote this but I am well and royally tired of everything. I still can't believe I got the career of my dreams and the education path I am interested in before I turned 25 even and im just wasting myself and my life what is wrong with me. I will obviously delete this account at some point but I really needed to let it out for a second.
