Hiatal Hernia Question

I've suffered from some digestive issues for several years including ulcerative colitis and a hiatal hernia. The hernia only really caused me some minor reflux in years past.

Recently, I've had several episodes that I chalked up to anxiety attacks but have noticed that they also seem to coincide with periods of belching and a heaviness/pressure in the pit of my chest that is very similar to the feeling I get when I'm startled by something...sort of like an "uh oh" feeling that hangs around all day. I also get pain in my back between the shoulder blades and extreme fatigue. I will wake up early in the morning with extreme anxiety and will shiver for several minutes and belch often.

Do hiatal hernia attacks trigger anxiety for others? I have been wondering if these periods of odd sensations in my chest are not pure anxiety but a reaction to hernia flare up and pressure in my chest cavity mimicking fear/anxiety response? Chicken/egg thing. Seems to last for 3-4 days then poof, gone. Really no anxiety outside of these short episodes where I burp a lot too. Anxiety and digestion very closely connected for me as I've found with my colitis flare ups.
