Kim - yes it is the same SIL, but the problems were mine not hers. With my PND I was unable to 'think outside the square' and put myself in anyone else's shoes. I was also blowing things way out of proportion. Now that I am on meds (and stronger ones), I realise that now.
Now that I am being more empathetic things are going better for me, and for other people in general.
I am still having my bad days, and lots of them, but with the treatment I am getting things will hopefully eventually improve.

RE work, yep its my old job in town. It would mean dropping Katy off at 6ish and picking her up at 6pm. On days when Mark is working an early or late she could be dropped of / picked up later, so it would not be every night.
