Maybe she just needs a break/vacation of some sort. Take some time off for her. I'm not sure it's attainable, but sometimes even if she does little things for herself here and there--it makes a huge difference. Also, maybe she is worried about everyone else all the time that she forgets herself. It can be easy to do--and then it all bottles up and then a meltdown happens and u realize u haven't had a haircut in over 2 years. (Surely not speaking from experience, eh hem...sarcasm). Not sure what her situation is like...but it's something she is going to need to do for herself...find ways to care and nurture herself thru time. Just a guess. Perhaps it's been a while--esp if the disability has been fairly recent...ie within the last couple years or so. Perhaps she's just now realizing how she is feeling after the aftermath of everything that's happened and changed in the family? Best wishes to u!
