@dyslexia,
Sorry that your having a tough time with family at the moment.
Since my sister died, my mum has removed the photo's of me and my other siblings from her purse and replaced them with ones of my sister, and on several occasions demanded to my dad that "The only daughter i want is dead", which is lovely of her. I've never got on amazingly well with her but she's gotton to the point almost denying she has other children. She then gets annoyed when my brother cries that she doesnt want him anymore.
Then again, a week or so doesnt compare to 5 years and I know thats not really the same thing but i just wanted to say i know how, well, annoying it is when a parent decides they don't want anything to do with you anymore.
Sounds like a crazy situation for you, but i suppose at the end of the day, it'll happen however. If i were you, i'd go ito selfish mode and forget about what the right thing is to do and do what you want, if legal rights and whatever stop you, well, you tried your best.
