I have a detailed diarrhea question I am very worried and need some advice. I have no insurence please help.?

I have had diarrhea for a week now that has been through a few stages. First stage was very bad abdominal pain and mushy mucus semi bloody stool. Then it was just mucus and blood. A friend told me to eat rice, bananas and drink Gatorade to gain back electrolytes. Now my stool is solid but soft and a lot of mucus coating it. My abdominal pain is back but not as bad. I am trying to self medicate but if it is something really serious I must find money to visit the doctor. I have a good diet and a none smoker. What could be wrong with me and what do I need to do? Am I getting better? I need suggestions please. Thank You for your time.
