Hi Miss Laura,
I agree with Pinny that the difficulty can be being honest with yourself before trying to rationalize or justify anything to anyone else.
Do you feel as if your therapist was being patronising with the statement she made?
Have you ever tried journaling? I'm guessing this suggestion has been made before (possibly ''many'' times, idk). That could be a ''safe'' space to write down (or type etc) exactly how you are feeling without fear or feeling of any judgment from anyone else. And then if necessary you could ''delete''/''rip up'' etc. what you've written which could in itself be somewhat therapeutic?
I have never observed ''hate'' from anyone on here towards you, I'm sorry you're feeling this way.
