"I thought my odds the first time were bad but my odds this time around seem virtually impossible. Yet, I find comfort in knowing that I am not the only one."
I felt exactly the same way. This is second time around for this M, and I had one D long before ever hearing of DB. There's been an OM each time. It is painful, and I had the same problems concentrating. Seriously worried about losing my job!
You have to put those doubts aside so they don't drag you into self-fulfilling prophecy. It's a fine line to walk between hope and the brutal reality of the situation, but that's the path the DBing LBS must walk.
