Hi abigail333. Welcome to ehealth forum.
I'm sorry to hear that you are suffering from so many problems. Please feel free to vent here. That is what the site and the people are here for- to offers answers, support and encouragement to one another.
That said, go ahead and vent, yell, scream, do whatever you feel is necessary. Then you must adopt a positive, optimistic outlook. I don't know how severe your case is, but a diagnosis of cancer is not an automatic death sentence. Unless your doctors have given you a terminal illness diagnosis- even then- you need to remain strong and fight this with everything that is in you. Life is beautiful and precious, even a diminished life.
You should visit our Cancer forum to meet and read posts by others who have had similar diagnoses.
Please continue to update here on your prognosis. And feel free to send me a private message anytime you need a shoulder to cry on. I will keep you in my thoughts and prayers.
