What OakLeaf said. Hang in there. You've got a lot going for you now -- a group of friends, your old job back, a familiar environment. Yes, you have to grieve the loss of your relationship, and you still have feelings there. But you're in a better place overall than before, with a better support system in place.
It will get easier.
