I know you're going to feel like you're not going to fit in everything that you have to say... but most importantly, be honest an thorough, but save the questions until the end.
It's best to go in there with a clear and calm open mind, let her do the questions and you do the answering. It's going to be tough, I'm not going to sugar coat it. but believe me, the second you walk out of that office you will feel like 100 lb sand bag was pulled off your shoulders.
In all honesty it's crazy to say this, but I had a lot of things written down, but it was just for my personal comfort that I wasn't going to forget anything, heck I even left the paper in the parking garage when I went up.
You will be amazed some of the information she can pull out of you, (events, situations, problems) that you never have even thought about since they had happened years ago.
If there is any place to be more open and emotional, cry for help in that office. You know that she can tell you what's wrong.
Best of luck to you!
Talking about addiction and side effects, medication in general...
They will most likely talk about the medication she wants to put you on at the end of the screening.
I spent a good 10 minutes talking to her about the side effects, addiction potential, how to take, when to take, what happens if the dosage doesn't cover it. will I be tapered off.
All those questions. but ask them. it shows responsibility and builds trust with your psychiatrist. I pushed mine a little too far... about 10 minutes past her 10 am appointment, but I know I had my bases covered.
