Anxiety is a strange beast. There was a period when I didn’t notice much mental anxiety but my heart would tickle and flutter, keeping me up at night. This is a common thing with anxiety. In the end a lot of physical ailments stem from deeply rooted anxieties. This is probably just a phase you will have to go through. Some other weird things can pop up like chronic nausea, palpitations, and most likely your stomach tremors. Try not to give it too much thought and power through with a low stress life style. I can relate with a lot of things I read in your history and I can tell you overthinking will only make it drag on. You are on the right track and while you might encounter some speedbumps along the way, you will get through this. Try to put your mind to that. You got this.
