Struggling to Find the Right Medication for My Mental Health

I need prescribed medication for my mental problems but have never been able to get on the right medication. Have to take over counter pain pills because my mental state causes immense body pains on a daily. I know it is mainly mental because every time i go to the hospital when i have a hard time breathing or in too much pain or for the times i passed out..the doctors have always told me i am healthy with nothing psychically wrong and recommend a therapist. The last time i had a mental evaluation done they told me a list of things i have and said that i can not get medication until i am further observed. This is my third evaluation and i been seeing a mental health expert as well. Anyone else having trouble with finding a place to help prescribe the right meds for you?
