Dull pain in stomach every time I try to sleep.

I haven’t been able to sleep without a sleeping pill. Everytime I lay down to sleep there’s this dull panic feeling that comes out of my stomach.. it’s been going on for 17 days.. quite horrible. I have been diagnosed with General Anxiety Disorder. I don’t think I can live much more like this.

My tests looked good for digestive issues? I am worried it’s my large colon.

Does anyone else have something like this..

Is this linked to anything?
