When your abilities are a part of who you are, it's hard to walk away from them, even if it's for your own good. I understand something about what that's like.
But a damaged memory shouldn't be too difficult a problem to at least assist if not entirely restore. Your mind, like the rest of you, probably heals, which creates like a metaphoric scar tissue. Creating like a barricade between the present and the past before the incident. It's just a matter of allowing the mind the freedom to recognise that the safeguards, the scars, are unnecessary.
