I would work on terminating for more than "next session should be your last." I would consider my T's thoughts and opinions as well as my own and my parents. Contrary to what your parents may be thinking, your T isn't automatically thinking to keep you as long as "possible" for the money it generates or some other T-type :-) reason.

A second thought is that, because you have the stress of finishing with school, you may want to extend therapy a couple sessions for the encouragement and structure of having a "bridge" to life after school. Having a couple major things happening at once, even if they're good thing, is still stressful so I would stagger them.
