breakups

I've broken up with my boyfriend a week ago today, I was at school on Tuesday and I saw him for the first ti since we💔, I ran away in tears cuz I miss him so much I got home and cried all night, I haven't been in school for 3 days now, today being my 3rd, I think I might be depressed because I can't get out of bed and I feel awful, I really need some advice because I really loved him and I've loved someone before and it ended and I convinced myself it wouldn't happen again and here I am, a mess again, anyone know anything that's going to help me get over him???
