I can relate to that feeling. Right before my last appointment I started trying to get EVERYTHING done at home and at work because I was scared I wouldn't be able to stay mentally organized after my upcoming session. I knew I had calmed down between appointments and was scared that I was going to "start back up".
I just tried to keep telling myself that I was just going to be more distracted and introspective; it's not like he was going to perform a lobotomy.
