After my last therapy I have regressed into a childlike existence. Please?

Okay, I by all means am NOT a mental health professional. But purhaps I can help. First of all, the 8 year old personality isn't helping you any. That leaves you with "doll collector shut in" and 60's dreamer. Now, pick one of those two that you believe YOU can function best with in society, with the least amount of change. Example, you pick "dreamer" okay, you loose the dolls, change your wardrobe, but function in a daily life outside of doll world! Say you pick doll world, that is fine, but you will have to adjust that personality so that you will be able to leave your house on a daily basis and function in life! Remember 8 year old HAS to go. The last step you will have to do may sound rediculous, but it gives closer. Take your 8 year old personality, and your other personality, either doll world or dreamer, and give them funerals. Write down everything about them like they are living people, memorialize them, write important things about them down on paper, then take that paper to a river or creek, (not a lake) moving water, and lay that paper in the water. Let the energy of the water carry away forever those personalities that YOU no longer need to function in this life! You are now stronger than an 8 year old, and you are now wise enough to choose who you want to be. Make you choice, let it be known.
