I'm 31 yrs. old, bipolar 2, battle severe anxiety disorder, and have ADHD. I haven't had any success with many kinds of medication and am terrified that I will never find medication that balances things out for me. I am currently taking Adderall XR, Lexapro and Seroquel. I know individuals who have had success with at least one of these but also have the realization that individuals have different chemical makeups. Are there any tests that a clinic can perform that will indicate levels of something in my body enabling a doctor to better prescribe medication for me?

I feel as though psychologists prescribe mediation in a fashion that mimics an "educated guess."
