Uncertain what to do.

Alright, as many of you know, I have been really struggling with the ulcers I have and the horrible pain they create all the time. I have been sick pretty much constantly daily. I had to call an ambulance Monday because I felt so bad and nearly fainted while vomiting. The worse part is that all they did was give you fluids and release me even when I explained I really REALLY needed something for the pain. Also, the breast lump I had removed showed stage 3 invasive breast cancer, but they aren't sure how to treat it because I am so weak and fragile already. My doctor claims he could break me in an instant or kill me with chemo if not very careful. They are suppose to be figuring out then whet I can do, but I feel like no one cares and if I were to die it would be easier. I am frustrated, disappointed, scared, lonely, and upset.
