what can I do

I'm still so broken, my ex broke up with me like 5 1/2 months ago and I'm still so broken, we dated for a year and I loved him so much, I still do. He just got into a relationship and it hurts so much, I really don't know what to do, I want to get over him so bad but I can't, I'm constantly crying over him and I know I shouldn't bc of everything that happened between us. i cant stand seeing him at school or thinking about what we used to be, it hurts so much. I just needed to let that out, does anyone know what I can do?😭😩
