It is great that you are able to give yourself a diagnosis. If you think you have diverticulitis, then a colon cleanse will definitely help you. You seem like a very bright person, so you have searched many websites for info. I have this as well and when I took the colon cleanse, I noticed corn in my stool. What was really interesting is that I hadn't eaten any corn since 2 weeks ago! That corn had been stuck inside for at least 2 weeks. So, it was obvious that the colon cleanse was working and able to clean my bowel. But, please discuss it with your parents. It really helps to get it off your chest. It's caused by an infection in the colon. And the infection in caused by undigested food stuck in there. If it gets really bad, you may have to get an enema to release the gunk that is stuck in the colon. And this usually clears up the infection. But, please try not to be worried about embarrassment if you have to go to the doctor. Think about the millions of young girls that need to go to a doctor and get naked for any reasons. It is something you should try to get used to anyways, because not long from now you may need to get pap smears. Discuss it with your mother and tell her you want a woman doctor if needed. You'll feel more comfortable with a woman doctor. You'll be just fine :-) Don't worry!! and take care!
