That is so true, I can totally relate. I could never have imagined I would get so attached to a stranger and feel so heartbroken when therapy ended.

What helps for me, is that I can be grateful for what therapy brought me. What I've learned, what I've become, how I felt "therapy loved".

Also, I made sure I got good closure. I asked and told my T everything I wanted to know and say. Prior to the final session, we both wrote down our view to my therapy and read it to each other in session. That was a beautiful moment that I think about a lot.
