Amelia, I'm sorry. It sounds so hard. I had real obsession stuff with my T, but for less than a year. I remember how consuming and exhausting it was, and I really feel for you.

Please don't feel bad for being manipulative. Of course you are trying to get your needs met. And the abuse you experienced was in no way your fault, not at all.
Maybe when you go to college, it will be a good experience in the long run. Presumably you could still contact your T and, as she says, see her in the breaks. So you have the reassurance that she is still there for you, but the distance to maybe break the transference a bit.
