I [19 M] am seriously struggling with the breakup of my girlfriend [19 F] of 2 years.

I was the one to break it off, but somehow I thought that would make things easier but it's really not. She had serious trust issues our whole relationship because of a previous boyfriend that fucked her over and I was left having to pick up the pieces and it got to the point where I couldn't picture my future with her because of all the potential stress and resentment I started to feel towards her.. but fuck man, I love her so much. I've blocked her on everything but we have so many mutual friends that I see her face everywhere and everytime I do it feels like I'm being stabbed in the chest and it sets me right back to the beginning. I know my friends are tired of hearing me talk about it, I've called helplines but I feel like I'm annoying them, I don't know who to turn to.

We've been split up just under a month ago and everyones telling me time heals all wounds but the days just feel so long. I haven't eaten in 5 days, I'm scared to sleep because all I dream is of her. I really need some words of encouragement to get me through this because this is by far the hardest thing I've ever gone through, and still going through. Please I really need some help right now.

TL;DR I'm struggling immensely with the breakup of my girlfriend and I really need help.
