Thank you for all of your replies, it's given me something to think about.
I haven't brought it up with T yet, even though it's been on my mind for several months. I think I've been saving this topic, because I really hope and wish that when I tell her how I feel about her it will be special and perfect (and slightly dramatic in my fantasies) If I don't tell her, then I won't be disappointed..
I think I've felt these things towards my T for a long time, but initially it was a childlike kind of love. I felt very dependent and needy. I still do sometimes, but I think now the love feels different. Maybe the love I feel has become more mature?

wow I feel really uncomfortable talking about love. I feel ashamed admitting to such feelings..

Take care
