This is a beautiful poem Waterbear and I think you describe the feelings you want to convey clearly and expressively. I want to say your feelings are highly relatable and your emotional honesty is inspiring.
I use poetry a lot as part of my own therapy and I think it is very valuable for those for whom it helps. I also think you seem to be doing really good work in therapy which is amazing for such a new relationship (it took me well over a year before I began to express myself this deeply to my T). I'm sure your T will value this wonderful poem both for its beauty and its therapeutic potential.
