Klange--
Hi and welcome to PC. I am sorry you are going through this and are feeling unhappy with your life. Break-up's can be difficult, and it can be hard to figure out what happened, or to try again. I hope that you will keep reaching out here and know that many of us understand depression and also breaking up.
Just wanted to let you know that you are being heard, not alone, and that we do care and are glad you are here.
