don't even look forward to seeing friends. depression...?

Hi...

I've been feeling down for the past few days and I haven't been eating properly. I just feel so full all the time I don't want to eat even though my stomach is growling. I sleep a good amount of sleep and yet I'm too tired to move. I've been getting these really bad headaches too they're even worse and I've had trouble sleeping on some days. I used to be find sleeping with the light on and now I have great difficulty. Everthing feels like a blur state like I'm in a dream and everythings going on without me. I can't even concentrate in school anymore without feeling weak and wanting to die. I imagine a lot that a few people would care if I die. I wanted to pull the trigger so many times but I can't do it. I don't even look forward to seeing my friends anymore and I just want to be alone. I did go through a hard break up in January. My ex dumped me on our three months for some girl and he lied to me. They've been together ever since and I don't know why my heart still hurts to see pictures of them kissing. He told me he loved me still but he loves her. She's been telling him I'm spreading sh** I'm threatening her I'm slapping her and cussing at her which I haven't done. He believes her more than me and I never talked to her I wouldn't waste my time. He stopped talking to me and called me a pathetic liar. He lives 2 hours away (changed schools recently) and people dislike her his friends do. They preferred me and not her. Recently her best friend asked me out and we've been dating since March 21st. I still feel heartbroken and upset even though I know I have him.We have a rule though we can't interfere with each other meaning if he's with his friends I can't be there and when I'm with my friends he won't be there even though I want him too... His friends don't like me because I'm asian (Filipino). Well back to the topic could I be depressed....?
