Is it possible i was sexually abused as a child?

I think the most telling thing that you may have been abused is the acting out with your dolls. Many times children will act out with dolls things that bother them they can't talk about. It seems since you liked being babied by your mom, the bed wetting could have been a symptom of that. You need to figure out why you liked your mom to baby you. Was it because your parents had another child that threatened to take their attention from you, did you feel some of your childhood innocence was lost or did your mom just have you spoiled & acting like a baby was the best way to ensure she continued? It's normal to feel more comfortable with a parent of the same sex bathing you, especially since your mom was probably always the one who did it anyway. Not remembering long stretches of childhood is also a sign abuse may have occurred. The eating disorder could have happened because of anything that made you feel out-of-control (like the divorce) & it's your way of gaining some control over yourself. Not everything you described points to abuse but some may.
