I am so sorry to hear your appointment didn’t go very well.
I used to have the same problem, I was not able to talk about what really bothered me, I could only write. Luckily I had a very good therapist, and I spent two years learning to talk, sort of.
What medication did he give you?
I think it is odd he says you’ve tried everything. Some may need a combo, and there are different combos that work for different people.
I just got a medication that is used primarily for schizoprenia, but also often used for bipolar.
I am so sorry you are struggling, hang in there- find a doctor that takes you serious and will help you get better.
