My weird feelings in my stomach when I get anxious I call "butterflies", others have stomach upsets when they are anxious and even get nauseous so it could be different for each person.
I don't think we can give you an exact answer for what your weird feelings are. I am sorry.
I hope you are doing better. If I get over tired I will get anxious easier.
I hope you get some relief and take some of the advice here and put it to practical use.
