Going to the ER for reassurance might not be a bad idea. If it's only been a couple of days that you're nauseous and having diarreah, then you just might have some kind of virus. Could be anything from gastroenteritis to the flu.
If you were in fact seriously ill, then you would be feeling really bad overall. We know our bodies better than anyone, so if you really feel that there's something really wrong, then definitely opt for the ER, and book a follow up with your GI and family Doctor. You should have a full blood screening done as well, and you might want to consider seeing a dietitian for some further suggestions on your weight.
