I had one of those nightmares last night.................very wierd, haven't had one like that since I was a kid.

You have been supportive, I don't have the nightmares as much anymore. (just wait for those), hope you are doing well. This whole thing sucks big time. Keep venting, and posting positive thoughts. It is amazing how much that helps.

The best thing to try for concentration at work, pretend the stbx is in a box and cannot bother you at work. It helped me about the half the time. I also warned my boss that my mind was not working and that I couldn't seem to push out the same volume of work as before. Thankfully that boss was understanding. Try to keep all of this out of your mind while at work, I know it's impossible but try. Also, start a journal of your thoughts and feelings, it doesn't have to be anything formal, and at the end of expressing your thoughts and feelings, if it is electronic you can choose to save it or not. It is rather freeing of the mind just to have that much control over something. Best wishes and be well.
