Ugh god I beg you

To help me get rid of this aniexty. I can't take it. I want to relax sleep, my mind constantly runs worried thoughts, I worry about everything, even things that aren't going to happen. I shake so bad my insides hurt, can't breathe, shiver. Cry, it's horrible been dealing with this since I was 11, and some days it's worse then others. I've tried breathing, working out, walking. Nothing worked besides medicine, but my doctors Won't increase or up my dose of medicine to just even help me focus. All I want is to be able to be ok and normal with the proper medicine. Any ideas? What I can tell my new doctor tomorrow.
