There are many times when those memory states that I live with are not around and leaving drawings and poems for me letting me know they are here but then days weeks months later theres the poems and drawing again. When I talked to alot of professionals about them going away forever I was told they will never go away forever. There is no way for them to leave forever and my still being alive and vice versa I can't leave forever and them be here without me. We are all a part of each other and we will all remain a part of each other. I cant change that and neither can anyone else by trying to force them to leave me. Talk to your therapist. That person will be able to explain it to you what is going on. so this process isn't so scarey.
