I've had severe anxiety for the past few months including huge palpitations and then stomach pain and acid reflux.

I was mainly worried about the heart palpitations, but once I stopped thinking about them they kinda went away. That being said, I still have lingering stomach pain (not that bad) in my lower rib cage. I've also experienced a similar pain while I was pregnant.. and google lead me to believe I have stomach cancer or gallstones. I will get it checked out, but at the moment I've convinced myself I'm dying.

Has anyone else experienced this?
