This might sound terrible, but I think my life is ruined now that my mother is confined to a wheelchair.
Why do you feel that way?
Because I will have to take care of her.
You shouldn't feel that way about your mother. She took care of you and now it is your turn to take care of her.
My mother is ungrateful and I hate her.
I'm sorry to hear you feel that way. People with disabilities can be fairly independent with a little outside help and by making the house wheelchair friendly. You need to call some agencies that provide assistance in these kinds of situations.
