Help with mother's liver cancer?

well my mom has had liver cancer for a little over 6 months. they were giving her chemo just to control the pain because it is terminal and that's all they can really do, they can't really shrink the cancer or try to cure it. But since she was weak last time she had her appointment (which was like a month ago) the dr. suspended her chemo till she got better because the dr. said instead of helping her it would hurt her more. I'm ok with that decision except that she doesn't eat at all, she says her stomach feels bloated all the time, and everything we try to feed her makes her vomit. All she has been drinking is Pedialyte, and that is not nutritious for her, it just kind of fills her up for a little while and now the biggest problem is that she is starting to get tired of drinking pedyalite. Anyone have any suggestions of what i should do?? How can i help her so that her stomach won't feel as bloated?? Any suggestions and help will be greatly appreciated!!
