I want to open this by saying that I will be making an appointment as soon as I can, but I’m wanting others experiences to help ease my mind

I worry a lot about dying or having a medical emergency, whether this is part of GAD, I’m not sure; however, what is really making me wonder if I’m developing GAD is that I’ve recently been getting nauseous. I know all too well that physical symptoms can arise without thought or explanation, so I was wondering 

Do you ever experience waves of nausea due to anxiety? Without preceding worry, just a hit of nausea (which in turn causes anxiety or panic)
