I used to desperately want to block the memories again, or at least stop any more, but I couldn't and it would only have doomed me to worsening depression, ill health and despair as I carried the trauma without dealing with it. Now I feel very differently. I think it's much better to allow the healing process to take its course and work with it (without trying to force it, as others have said).
Even though we can't repress the memories again, I think there's a big temptation to repress the healing and - unfortunately - that can be done. It can be exhausting, terrifying and awful to actually face and deal with what comes up, to go through the doubt, fear, grief and other unlovely feelings that are part of finding our way through. But in my experience, trying to hide from memories that have surfaced brings as many problems as trying to hide from those that are still repressed.
I think we're meant to heal and our subconscious minds know when the right time for that is. Although we might wish deeply that we'd been given a different experience of life, I don't think there's any good alternative to facing it.
I'm still working on this, but I've come a long way from where I started. I'm glad to be in a much better place now, and definitely a better place than I would be if I'd repressed the memories again. For all the struggle, moving through it can also bring new understanding, meaning and connection, perhaps in a way we couldn't otherwise know. I would never say I'm grateful for the trauma, but I'm grateful for the healing.
