It's been helpful to me to have a conversation with my younger self/feelings, which means I have to acknowledge them and accept them as reasonable given her limitations. Sort of like the Gestalt "talk to the chair" (which I actually find stupid), I reassure my younger self that it's normal to be resentful and angry, but that T is trying to be helpful and is there for us in so many ways (describe them).

But that also means accepting that sometimes these feelings will not resolve completely, or will take time to resolve, and that it's normal for them to come bubbling up when you least expect it. Just around the time I've accepted that I'll always feel ____, they seem to dissipate.
