I posted this is the depression forum and someone directed me over here so here goes...

I slept with a co-worker after we had flirting for a few months. We finally ended up going out one night and we ended up getting intimate. Now all the flirting is over with and he hasn't attempted to contact me at all. I still see him at work every day and we make polite chit chat but that's it. I am so humiliated and embarrassed. I know I should have known better doing that with someone I work with but from all of our conversations I never thought it would end up being a one night stand. It's been almost 3 weeks and I cry every day. I have dealt with depression in my life before and this feels like one of the worst things I have ever gone through. I feel so worthless and unimportant. I want to scream at him or send him a nasty text or email asking him why he did this to me. Obviously there was something about me he didn't like or I would have heard from him. It is the worst thing having to see him at work every day!

I also am a little obsessed with him and do things like go by the gym he works out at to see if his car is there or check to see when he goes to lunch and with who at work. I feel really crazy right now and any advice on how to cope with this would be appreciated.
