that part about giving your room to your brother I can kind of relate to, when I moved out of home at 17 my 15 year old cousin who was doing all these drugs and running from the cops decided to stay with my mother, she gave him my old room and said if I ever wanted to come back home I had to sleep on the couch because my cousin had my room now. Like you we've moved on and she has apologised from it but a lot of resentment is still there, I had a choice out of sleeping on the couch at my alcoholic mothers and cousin who was dealing her drugs, or living in a half empty house on $79 a fortnight and sleeping on wooden boards. I chose the boards.
