Lily99,
I'm sorry to hear you had such a rotten day yesterday! I know the awful feeling of being in pain or need and having people ignore it. It really hurts, doesn't it?

I want you to know that I care about you.
I can also understand why you would feel upset and sad seeing your t with one of her clients who is a young person near your own age. You want to believe and know that your relationship with your t is important and unique, not a carbon copy. If it helps you feel any better, my t told me once that although she cares about all of her patients, each relationship is different and unique and important to her. So even if it is hard to share your t's attention and caring with other clients of hers, at least know that none of those other relationships takes away what you have with her. Her caring about them does not make her care about you any less.
