Jim, I hope you find your meeting helpful and it puts you on the path to recovery!
I have some practical suggestions.
Take a notebook with you and a pen to write with. Make notes of the meeting and anything that is suggested or promised. Time can be short, and sometimes emotions stirred up, so afterwards it can all seem a blur. So if you have it down on paper, you can get past that. Sadly, I've had the experience of a psychiatrist promising me a course of treatment, then withdrawing that offer. Having the evidence meant I could complain and get the treatment that I needed. I wish I could say that it was a given that they had your best interests at heart, but it isn't always the case.
I find I spend a great deal of time in first meetings (and often some subsequent ones) giving a long history. So I've written mine up, so I can just hand it to them. You could also get it to them in advance of your first meeting. There are two advantages to this, firstly it saves a lot of time, and you can move on more quickly to being treated, the second is that it can be emotionally harrowing going over the history (mine's long and complicated) I find it enormously better not having to go over it all unnecessarily.
If you have someone you trust to go with you, that can help too, they could take notes, help get things clarified for you.
