"I also feel that I have done A LOT of thinking over the past 6 months months, since BD. I have analyzed everything to death and thought over every little detail a million times."
I know that process well. In my job, that's pretty much a requirement, so transferring the process to my sitch was only natural. If W does this, then this and this could happen. Then I'll do such and such. Plan A, with contingency B, Option C, and so on and so forth.
I did it so much my mind would go numb, and that was a close enough substitute for detaching that it would at least let me get some rest.:-/
