Childhood trauma

How do you actually cope with childhood trauma? I seem to forget my whole childhood and everything does be fine until every now and then I find myself lying in the dark in hysterics with all of these memories just coming back at once and in moments like that I find it difficult to breathe and as if I can never live a normal life after all of the things that little me went through.I wish I could just give her a hug.Does anyone have anything that they do to heal their inner child?(Other than therapy or speaking to “loved” ones?)
