Medical question.........:\?

So I have been having diarrhea for kinda long time. At first I thought it was kinda normal cuz my boyfriend broke up with me and id feel queasy every time i thought about it, and i had diarrhea a lot. but now, its been a few month, and sometimes i feel a little queasy, but i have diarrhea all the time. Is it a major worry in need of medical advice, or can i just wait it out?
