Struggling with Multiple Diagnoses and Medications

I just wish to have 1 diagnosis. because everytime I see a new doctor I get a new diagnosis and new medication. I just know I have mental disabilities and every doctor wants to give me a different diagnosis. so how am I supposed to be ok with that. I've learned to just stay busy so I can hide how I feel inside. I just want to be properly diagnosed with something rather guessing what's wrong with me. I do know I have mental issues. and being drugged up only masks the issues and can't properly be diagnosed. so if anyone has any ideas on how to get proper treatment let me know
