breast cancer

I haven;t been in for a while, it seemed everything was going wrong. I couldn't even remember my password. M y cancer is back I go Tuesday for a biopsy. I have been fighting a rash they don't know what is causing it. This time I havr to go to cancer care in Seattle for there advice. They said my skin was already pulled so tight and they have to go in again, this is the fifth or sixth time. I have to see a plastic surgeon and see what area there taking muscle from to fill in the hole in my chest, and the skin graft. They said I could have stronger pain medicine I said not now. I feel so weak and fall asleep fast. Has anyone had this before and how did it go. I'M scared. all help appreciated.
