I'm sorry to hear it. I won't go into the whole story here but you can easily find it by searching my posts; just over two months ago, I experienced a drawn-out and traumatic end to a two-year relationship. It's been devastating. Time really does seem to be the only thing that helps much - I'm not curled up on one of my couches alternately crying and staring at the wall every day anymore, but it still hurts a lot.
I've been trying to go out when I can, spend time with friends, make time for myself, and avoid things that will trigger feelings of hurt, abandonment and resentment (like old messages and photos.) It's difficult in different ways every day, but I'm getting through it (I really have no choice.)
I hope that things will become easier for you, and I know how hard it can be to experience something like this when you're not out to friends or family. Some of my friends noticed that I was very sad, and assumed that my husband and I were getting a divorce. So I've had to do some explaining.
