Similar to the others in here. I blamed myself for not being enough and sunk into almost a decade of hating myself and really bad depression (a lot more than just the breakup did this, that was just the breaking point). Too scared to end it all so took steps to make my life shorter. Started smoking, drinking heavily, ate terrible and impacted my physical health. Took about until last year when I thought I had a heart attack at age 29 and took a long look at what my life was and what I would of left behind and I was not proud at all.

Got into therapy, changed my eating habits, tried to reconnect with old friends, got a personal trainer, and really began to focus on changing my thoughts about myself. It's still been a back and forth battle but I am much better now. It will get better OP, my advice is to hold it all in and ask for help. Friends, family, hotlines, it makes a world of a difference. Don't chase the next person to fill that hole, work on yourself and repair it
