I am very, very sorry for your experience. As you know from all the pros you've talked to, the individual who did this was irresponsible and wrong.
I did not realize it at the time - I thought it was normal! - but I was very fortunate to have a PDoc who listened to me and treated me more like a colleague than a patient. He knew that I needed his medical expertise, but that he needed something from me, too - the "data"! The first visit, he explained to me that I was never to assume that he was right and I was wrong about any medication. It was like an experiment we would run together, and if something made me feel worse or didn't help, I needed to tell him honestly and not assume "doctor knows best." and that's what we have done, since I was 17. It has been trial and error. He would tell me the side effects, explain what he believed the benefits were for me in particular, and ask me, "What are your thoughts?"
I wish every person could share this experience when it comes to mental health.
