hi i have terrible health anxiety and undrgoing therapy for that but my problem is i think i have bowel cancer, i have pain under my ribs, on the sides and my lower middle back, also today i found browny discharge when passing a stool, i also thought i saw blood but i checked and think it was pieces of food as they seemed hard, iam that bad i got my mum to check for me, she says she gets that but i think shes saying it to make me feel better but she says shes not, ive been to 2 different doctors twice they felt and listened to my stomach and everything was normal , my temperature was fine, i havnt lost weight but i have a feeling i have cancer and everytime i think about it i can have panic attacks everyone tells me i dont have cancer but it wont sink in, cancer is my biggest fear im scared of dying, im 19 and cancer doesnt run in my family, please help, thanks, im female, my stool can be very dark brown/reddy orangy colour
