CAnn I do not know what to say every word you've typed I've lived. I know how overwhelming all this can be. From Your post it doesn't sound like you have a supportive family, this is very sad, I do not know what I would have done without mine. I'm praying that the family can overcome it's differences and come together, you are going to need all the support and help you can get. There are agencies that help, seek them out you cannot do this alone.
Be strong, dig deep the strength is there, you are all in my prayers. If you need to talk PM me.
