I don't think your goals sound too lofty at all, but you need more regular support than you had before, 10 sessions over 6 months is hard to build much consistently on...although it sounds like your scheduling options are complicated, as in, you don't have much of a choice.
My goal is to work on grieving/loss and letting go, determined by myself and not my Ts, although they agree this is a good goal (I have two, working on getting out of therapy with one and into therapy with another). I know my depression started with a big loss in 2010, although I was already prone to it with a very high anxiety level, previous losses I had not really dealt with, plus I am quite OCD.
Anyway, I hope your next appt. with the nurse practitioner goes well. It sounds like you know what to ask for help with, you just need the right resources to give it to you.
