I am listening .. quietly, James.
I am not quite grown up either, I used to get upset about this, but I dunno, for me I think I am ok, my child bits feel like a veil of goodness, protection and I would rather not let it slip into the night.
I have no idea how you feel about what you are going through, or what exactly it looks like to you. I am very much not my age, I dunno tho sometimes I feel soooo old, like an old person in this weird body, my mind feels old, but on the other hand un-grown, I never did get to grow up, forever old and forever a child, and never in the middle.
Sorry, just " I hear you".
