It's perfectly normal to go through a period of hyper-vigilance and spying. It's always okay to go back and double check on things at any time, too. Like you, I ended up dropping the majority of my spying after several months of not finding anything new. Another key when it comes to this is to listen to your gut.
The fact that you went into counseling immediately is a good thing.
Not everyone can do it, but I think uprooting and moving is probably a very good positive as well, especially with the OM being a co-worker.
Best of luck to you, and keep us posted on how things progress!
