I have never had IBS but during my extreme CC anxiety and 2 weeks leading up to my colposcopy I had a huge change in bowel habbits. I had very thin stools that were soft and thin, yes almost pencil thin stools during my extreme CC fear. I have always been more of a constipated hard lumpy stool kind of gal (tmi) but during that horrible horrible anxiety I was having a whole mess of different bowel movements soft, skinny, yellowish, semi runny you name it. I also had a lot of gas and very loud digestion. All anxiety. I even had BLOOD in my stools that's right bright red blood for 15 months periodically. I like you spent every waking hour on googling trading stories about people my age with CC. I made my self I'll. I was convinced I had it no doubt. I was a horrible mother to my 4 children and I horrible wife to my amazing husband because for a year I had my face in google reading about CC, DAILY. Guess what??? I wasted 15 months of my life over it. I was proven by a doctor to not have it. Trust me Daniel I still struggle daily with health anxiety. I was in the grocery store today walking the freezer isle thinking what if I started having a hard attack right here in this isle?? Seriously I'm a wreck and sadly have lived my while life this way. You are 19. Please seek help for your anxiety. I am still in the process. I have 4 young children so it isn't as easy. I say I'm 99% sure you don't have CC. I know you are like me you want us to day you 100% don't have it but we can't only a doctor can. I really think you need to get a colonoscopy and put this to bed. Save this stress for when you are 60 or 70 and need to me more cautious of pain, not your teens and early adult life.
