Thanks for replying, SecretGarden. That's good it could be done independantly of my parents...if it costs money, though, I'd probably need to tell them. They don't mention anything about costs on the website - I'm not sure if that's because it's free, or if the cost changes according to circumstances?
Thanks.

And don't worry about being repetitive!
Yep, that's right. By the time I'd emailed my therapist, though, I had decided that I didn't want to end just yet...I'm surprised he didn't ask about that, to be honest!

Probably a stupid question, but does "self advocate" mean the same as "assertive"? I've never been too good with that - spent a session on it in therapy, and it helped a bit, but I guess I've still got a ways to go.

You could be right there.
