There is nothing wrong with setting your own boundaries and keeping to them. You do not owe her any explanation.

I'm not saying that putting boundaries in place is easy, because it isn't, and somthing I struggle with myself.

It is hard sometimes to remain firm, particularly with those we are close to, or feel some obligation towards. Whilst you clearly have been there for your friend, there should not be any obligation to allow her to trample all over you with demands if they don't feel right to you.

Saying that she wants you to 'remember for your sake' seems a rather odd thing to say. I would not expect even a mental health professional to say something like this, let alone a lay-person. Pushing someone to remember a traumatic time without the approriate support in place can do more harm than good.

Take care @willowtigger
