I'm 13 and male, pretty healthy in general. For some reason, I've been really anxious the last 3 and a bit months. I did write a post yesterday but that had lots of symptoms and was moved to that category and is now pretty dead, so I'm going to keep this one short.
I'm worried all the time that I have bowel cancer, that I won't live long enough to see my relatives in China next year, and that I won't be able to live my life anymore. Why? Many things (but that was on the other thread), but the main thing is a constant feeling of pressure in my rectum, like I still have poop to poop even when I don't. This might just be constipation, as whenever I do poop (every other day, usually), it's either dry or slightly dry, and it's many days' worth of poop (I also eat quite a lot, but I'm still of a good weight), but I've seen way too many articles saying it's a symptom of late colorectal/bowel cancer. Tack on some pain and some feelings of weakness, and I'm convinced I've got cancer.
I know that the chance of me having it is practically impossible, and that blood in stool is the hallmark symptom, but I just can't shake it off. During the day, there are many times where I feel like I'm going to just die, and think about all my relatives, stuff, lost opportunities, all that, and almost cry.
EDIT: my parents are aware of this.
