Holy $hit, Pho. Losing my dad was tough (nothing compared to BD), but I can't imagine watching my kids suffer like that. I'm glad they are thriving now. No thanks to your H. Your kids are very lucky to have you. In your previous descriptions of how you deal with your D, it's quite clear you are a wonderful mother.
No HR for me. I quit university, no degree here. Even if I wanted to go back to school I certainly couldn't afford it. Financially and time-wise as well.
