I agree with everyone that therapy will only improve her quality of life but I completely understand if she feels like she's not ready for it. A big part of therapy is addressing/opening old wounds and suppressed feelings and memories that were buried in the first place because they're incredibly painful. Therapy is hard work and anyone who does it and comes through it should be applauded for enduring a great personal challenge. Going to therapy took me years and completely changed who I am on a fundamental level.

Something that would have been helpful for me in the past would have been to be reassured that I can start out very lightly, as little as I want (like just meeting a counsellor to feel out the room. Dipping a toe in) and that I'm in control and able to retreat if I need to.
