Been there, felt that.
My first broke up (I was 20 at that time) was horrible. I didn't even know that such emotional lows excisted. I lied in my bed and what ever I did, where ever I went, I couldn't hold back my tears if a sudden flashback or memory hit me.
What really helped me back on my feeth back then was a new female friend I had back then. There was nothing sexual, we just mainly texted a lot and talked about everything. I couldn't feel anything for her at that time, but looking back now, having her was what really helped me to overcome the break up.
Worst thing holding me back was the tought that I could ever find anyone as good as her. But as time went by, I met several just as good people, some either better.
Since that I've broken up twice, and everytime it's the same pattern - heartbreak and tears. But eventually, time heals. I can't give you an exact date, but slowly it gets easier. Try to socialize with new chicks. Nothing serious, but something to remind you that there are other women out there.
And I promise, they day when you kiss that new person who sweeps you off your feet, then it all makes sense. And it sure is an amazing feeling.Then you will also see how you survived through that darkness too.
You can make it buddy. We all been there, we've all felt that.
