Absolutely true. Also, OP, consider that with the right therapy and support, in the future she may stop meeting the criteria for the conditions. It's still early enough for her to learn how to explore her identity and accept her history. It is different for each person but I think was caught early enough. No person is trauma free but you're there for her, you did your best with your resources at the time and you're doing your best now.

Not a fuck up. It's admirable what you're doing.
