Wow, your psych. pegged my situation exactly! We are in similar spots in many ways, so all I can say at this moment is I feel for you. I was in a down spot a couple weeks ago, but fortunately it passed after a few days. We never know when these down days will come, and we don't know how long they last. But, my experience is that they do pass, or at least get better, if I am busy with other activities and remind myself that I, and only I, am responsible for my own happiness each day. It doesn't depend on W, kids, boss, etc. It depends on me.

Keep posting; it helps to vent on these boards, even if the answers aren't clear. Sometimes we need to just sit with the hurt, and not look to run from it. Face it, feel it, even welcome it as a way to understand ourselves and life in general. I keep trying to ask myself "What is the lesson(s) I should be learning from this?" The answers aren't always clear, but I've been separated for several months now and really tried to work on myself, and I take great pride (though not in an arrogant way) about how far I've come. No one can take that away from me, no matter what happens with W.

Try reading Pema Chodron. She's really insightful about dealing with the pain of life rather than running from it. And keep asking yourself what you need to learn to grow as a person. And hang in there. This is damn hard.
