Hello - thanks for asking your question.
With chronic watery diarrhea and left lower quadrant pain, it is worthwhile to obtain some kind of endoscopy - either a
colonoscopy or flexible
sigmoidoscopy. Stool tests for malabsorption, bacteria, ova/parasites should also be performed. I would also consider tests for malabsorption, such as a fecal fat test, or tests for celiac disease.
Causes can include inflammatory bowel disease, a chronic infection, or malabsorption.
IBS is a possibility - but one has to be sure that the diagnostic tests are negative first.
As for the home occult blood tests. They are pretty good, but no test is 100% accurate. For instance, taking vitamin C can give a false negative result.
As for the dizziness - if you are having profuse diarrhea to the point of dehydration, that can be associated with the dizziness. However, without examining you I cannot be more specific.
Followup with your personal physician is essential.

It would probably be a good idea to see a doctor even though you are scared. Just explain your fears to the doctor you see. Most doctors are very understanding about anxiety with regard to being examined, and simply explaining your anxiety may help you to feel more relaxed.
Stool analysis (whereby stool samples on consecutive days collected by you in a special container and brought to a laborartory) can tell if you have some sort of infection, such as a parasite or other infection that has caused the recent change in bowel habits. Gastrointestinal bleeding is only one marker for more serious problems such as cancer, and is not sufficient as a diagnostic tool without having further evaluation in the presence of altered bowel habits. A gastroenterologist will ask you about your family history, including whether or not there is a history of cancer, inflammatory bowel disease, irritable bowel syndrome, diverticulitis, etc. He/she will then be better equipped to make decisions regarding which diagnostic tests to order, if any.
Good luck
