Hello, I’m Afraid There Could Be Something Very Wrong With

Hello, i’m afraid there could be something very wrong with me. I am having stomach pains especially when I exercise. I am used to exercising often but I can’t even exercise a little bit without a lot of pain. I haven’t been able to eat as much. I am always very tired. I am having blood in the stool and sometimes a lot of blood. And I when I’m not I haven’t been able to go poop for days. But I don’t want to go to a hospital.
