I've had problems with my stomach for years now. It's never been bad enough to go to the doctor (mostly due to money too) but recently it's really been bothering me and i don't know if it's worth a trip to the doc.

Symptoms: Lower abdominal pain(Sometimes very severe), diarrhea(every week at least 2-3 days a week. since this morning it's been clear diarrhea), constipation,  loss of apatite, and fatigue.

Please help!
