My T doesn't really push me to do anything. If I tell him I'm lacking motivation we talk about whatever it is I'm not doing, why do I want to do X, how do I feel about it, what is getting in the way, etc. etc. Sort of like motivational interviewing but not pushy or anything. It's up to me to push myself.

You could probably talk to your T and ask her if she could help you with goal setting and accountability and stuff like that.
