I think everything your feeling is normal considering your situation. Divorce is horrible on anyone MI or not. I feel you did yourself a wonderful thing by passing on the other job right now, you have a understanding boss now, maybe the new one would be the reverse.

Be easy on yourself.. I cried off and on for a very long time after my first marriage ending, It's normal. Maybe try a set treat for your self every week , something to look forward to .. a manicure? a favorite dessert? something little, something to just look forward too, It just helps during a stressful time.

Take care
