Regarding the +rep: no problem at all. Been there myself just a few months ago. I heard his favourite hymn (which was played at his funeral of course) the other day and had to sit down and have a cry.
I'm a bit late to the party, but has your mum left the invite open ended? You could try some time with your brother and if it doesn't work (or he has to move and you haven't got yourself sorted out), move in with Ma and Pa.
