How does a conversation about schizophrenia go with proffesionals?

I suppose either psych or therapist. My main conversation was when I was getting diagnosed. Basically was told I had it and then I moved and haven't discussed it other than trying medications. I don't mean conversation about how your new med is or isn't working but others.

Do you go into details about your psychosis or symptoms? I've been in therapy before for plenty of other things so I'm guessing it would be similar but there are a few mental illnesses I have that are hard to discuss with a proffesional because I feel like they simply could not comprehend what it's like. If you talk to a proffesional about it, what is it like? Are they nice? Does it feel like they understand? Do you keep it to yourself instead? Just wondering. Someday when I get a new therapist I would give it a shot but not able to at this moment.
