It strikes me that these are all just thoughts, and thoughts do not need to be given great or even any significance. For example, I do not see why you are "ungrateful" for having thoughts about wanting more from your therapist. It seems like you are being hard on yourself.

What has worked for me when my thoughts are bumping into my present (usually nice) experiences is to just allow those thoughts to exit in the same way they came. Sometimes I imagine tying them to little balloons and letting them float away. It might be that meditation has taught me that thoughts come and go, and made it easier to let them go. And that I can choose which ones I focus on.
