My gf just decided to break up after almost 5 months of relationships (it was my first).
It was a long distance relationship and we were only able to see eachother every 2-3 months and we had to kinda organise the schedules to see how much time we could stay together.
Some days ago I went to see her again (for the second time) and she was kinda cold and wasn't really making me feel loved but I didn't say anything and from the moment I left with nothing but a sad kiss that didn't taste the same I thinked about it everyday all day and eventually today she proved me right.
Now I'm alone again, the only thing that made me stop overthink is gone and all because she wasn't ready for a relationship
In these days I've come to the conclusion that people like me are probably never gonna be happy cause we're just incapable of living life and it hurts a shit ton to wake up and realise I'm still here for another day.
I used to think time solved everything but all it's leaving me with is a necklace with her initial that hurts me the more i think about it
And what sucks the most is that I was there for her whatever happened, failed exams, mood drops, panic attacks before exams or just in general, I was always there to support her and now she just says "I'm sorry", as if her apology meant something.
I tried my best but she still left cause it felt like I was stressing her with expectations and what not.
Idek if what I said makes sense
I'm just lost and hopeless cause I know I'll never be happy
And if that wasn't enough I have exams in less than two months and these exams will determine if I will manage to get a job or not cause nowadays it's hard to find one so I'm more stressed than ever with no will to live or get out of bed.
Just the thought that if I don't get a job I'll have to study and get certificates makes me not want to wake up tomorrow

I know I need to do something about it but idk what to do or how to push through this, I feel tired and idk if I have enough energy to deal with it
Please help me get back on track, I know I'll fall a lot of times but I've never felt so lost in my life
