Is this IBS? Or just anxiety?

[Librella]

I've been having stomach problems for about 3 weeks now. I feel something like a gas bubble in the same spot beneath my bellybutton, bloating, and digestive problems nearly every day. I thought it was just PMS but that has passed and still have problems. I've had stomach problems a lot before, but never the persistent pressure feeling in one spot.
I mentioned the problems to my doctor and she thought it was PMS and stress, but should I go back if it continues? I'm scared of the tests I might have to do. It's so hard to tell what is anxiety and what is "real" health problems. I've been having a rough time lately and obsessing over these problems.

Hi I have been dealing with indigestion with burning between breast and neck have diarrhea for 2 days. Seems my anxiety it at high level lately. Does anyone have this too? The more my mind focus on it the more it burns. I tried gas x but now the diarrhea. I have been eating ginger lately because that seems to help. Unless i ate too much. I tried breathing and helps a little. I just needed to talk to someone that feels this way too. Thank you.
