I amd 19 years old and about a year ago i posted about how i was scared about colon cancer and that i had blood in my stool after being constipated for a week and straining to try and go every day i was constipated. Now, a year later I am still having the same blood in my stool, it hasnt changed at all and up until now that was the only thing abnormal about my stool. I went pretty regularly, and the size was normal etc. Lately I have had pretty thin stools, but sometimes they're thicker than others. They have also been kind of feathery and not hard, but not watery at all. I have been having awful heartburn and indigestion and its been pretty miserable. My family doesn't have a history of any kind of cancer really, but they do have some general GI issues like IBS and Ulcers, etc. I feel like i am more tired than usual, but i am wondering if that is just depression over not knowing whats wrong is me and being scared to find out because when im doing stuff and hanging out with people i feel fine. Someone please give me an idea of waht might be wrong with me!
