I'm so sorry about your loss.:( it's horrible to have to make a decision like that,but no matter what,i'm sure your aunt knows how much you loved her,and how sick you are.this disease takes so much away,it's a nightmare,i'm so so sorry you were in that situation.:(
and about the school stuff. i know what you mean! i'm trying to deal with university right now and it's absolutely crazy,but we've just got to do the best we can. have you ever considered taking any online classes?
and about your aunt's son..I'm so sorry for him too. my mom died when I was young,she had a brain tumor. I was too young to really understand,and it was and still is one of the hardest things I've ever had to go through,but I know she's in a better place. I know it's so scary and you must worry constantly about the little guy,but he'll be okay. just be there for him,that's all he needs is the love. :) it helped me more than anything just to have the people I loved there with me to help me cope,and love me unconditionally.
and new shiny,I'm completely jealous,4 weeks paid vacation time?? :P gl guys!
