As much as this will be the last thing you want to hear, the biggest favor you can do for yourself right now is 1) ditch the alcohol. 2) let that girl go.

Focus on other things in your life to distract yourself for now (that is NOT booze obviously :P) Join a gym, start running, get into a satisfying and fun hobby. Lean into friends and family for support.

The sooner you do both, the better you will feel. I know its much easier said than done (on both counts), but one day you will look back and this heartache won't feel nearly as bad as it does now.

It may not feel like it now, but one day this will be far, far away in your rearview mirror.

Best of luck to you.
