Do i have aids or is it just me?

Well if all you've had is diarrhea for a few months i doubt you have AIDS. Everyone gets a bad case of diarrhea every now and then. Just start eating some foods to harden your stool a bit. (like cheese) And getting tested could help but it also cannot help. AIDS/HIV can be asymptomatic and not show up on a test for up to 10 years and if you've had was diarrhea i highly doubt that's what it is. If your still worried go to the doctors and see what they say.
