Thanks for replying, ECHOES. It is a bit sudden! I need to email him, but I don't want to sound rude by talking about finishing.
Those are both good points. I think one of the problems with keeping therapy up after finishing school is that I'm supposed to be finding a summer job, and I don't know if I'd be able to fit sessions in with the hours I'd have to work, especially as I have a few other things on in the evenings as well. Sometimes the dates of sessions are a bit unpredictable, although I've managed to have the same time for the past month or two.
I'll try and do that. I didn't say when they suggested it that I wasn't sure if ending it was what I wanted, which was a bit stupid of me.
Thanks.

My dad's response when I said I didn't think I'd be able to do sales work as a summer job was "what's wrong with you? You're normal, you're not special, anyone can do work like that"...I'm hoping that's not how he meant it to sound!
