TBH I kind of felt that your T might have looser boundaries than what is considered the norm. However, every client has special needs and given that you're underage (child therapy has generally looser boundaries than adult one) she could have been doing what was best for you. IDK.
However, your wording:
' It was one of those relationships that don’t come around very often. It was one of those that some people search their whole lives to find. If you have found that person in your life, then you understand where I am coming from'
sounds kind of spooky to me. Can't really put a pin on it but this is a client-T RS you're talking about and it surely shouldn't be one of those that some ppl search their whole lives to find...
Anyway, do your parents know you haven't received individual therapy there? What was the reason behind that?

Plus, and this is just me, but please, be careful how much info you share here- it still IS an open forum and I would strongly encourage you to change names when/if you're using them.
