Sorry I haven't checked in recently a lot seems to have happened in the last few days. I don't think it was a smart move for your step mum to contact the practice manager. Or for you to meet with the practice manager in person. The practice is shady and biased... to protect yourself from further manipulation you need to deal only with unbiased independent people from now on (eg your psych, a government authority).
Please do not go pick up your records by yourself!
On the upside this could be a turning point for you. You are being so strong throughout this! There is a challenge and you are rising to it. And it seems like your psych has YOUR best interests at heart and will be able to help you get better.
It may not seem like it at the moment but I think this is a big turning point in your life getting better.
Stay strong and best of luck xxx
