stomache and nausea natural health remedies?

Lately i’ve been having stomach issues.
I am usually nasuseated a lot at night no matter what I eat and I sometimes often get a stomach ache in the upper area in the middle.Its not a sharp pain just a aching pain.

I’m not sick nor do I think i have any viral issues because its happening often.

im not pregnant nor using drugs.

cant see a doc for a while.wondering what kind of digestive/intestinal issue this might be.

I also have anxiety lots of the time.could this be the reason?
