About 3 weeks ago, I was laying in ved, and suddenly felt pain in my lower right side, went to a doctor, had it tested, it wasnt appendicitis, but I drank some water and the pain went away (it has been over 100 degrees here since the beginning of may, so ive been drink alot of water, 3 weeks later, I had bo appetite, which sorta came back for a few days, but its been going in and out, plus my bowel movements have loose stool with slimey liquid, no blood except a raw anus, which happens often when this happens to me, and im scared its cancer, but I had a blood test done back in november 2013, they said I was just fine, and which according to my mother (who is a hospice and RN, a nurse) says they would have found something, ive had no nausea, vomiting or pain, now in terms of stress, at the time this started, I was worrying about school, family and a few other issuse's, I have the feeling like im falling appart, ive even broken down crying a few times ...so is this cancer or just stress/depression?
