Hi Smilie
I don't think it really matters if it's an alter or just inner child feelings. The thing that matters is comforting this part of you. Might try a coloring book, watching a cartoon on TV or renting a good movie the inner child might like. Set aside some time to just be with the inner child and comfort them and let them know how safe they are now.

I don't know if it's a form of dissociation or not. Just try and care for this child who's sad and cries.
