Idk what else to do. I need answers.

22 female. 170 pounds. I take 40 mg of Prozac for anxiety and 10 mg of hydroxyzine as needed for anxiety. 20 mg of Pepcid for heartburn. I vape nicotine. I’ve gotten about 5 EKGs within the past 2 years. I’ve had an mri of my brain. All came back clean. They always say my CBC blood count is normal. A1C normal. Cortisol normal. But I’m constantly feeling sick, dizzy, lightheaded like I’m going to pass out, shaky, weak feeling like my body is jello. Even when blood pressure and sugar are normal. 124/76 was 2 days ago when I checked as I was feeling this way. I’m just so lost. I never feel good anymore. And my doctors don’t want to do anymore testing.
