Hiya.. I hope you are feeling fine, It sounds like that you have alot of questions that you want to ask your psychologist, I suggest that you write a list of questions that you can take there.
This is because when I went to see my therapist I forgot half of what I wanted to say and I was annoyed when I went home. Also you could write a list of your symptoms and feelings, I did this and it helped me.

My opinions on medications, they helped me very much but at times I got some bad side effects, but its about finding ones that suit you. I'm currently taking abilify and celexa

Yes I think that you should ask her about your diagnosis, however some psychologists are reluctant to say for some reason, well they were in my case.
Because it took them 2 years to tell me my diagnosis, and ive recently been diagnosed with schizophrenia.
Good luck with your next visit, and if you want to ask me anything or talk feel free to ask.
