just a quick suggestion - everyone whether they have a mental problem or not has what the mental health community here where I work and live call having an inner child. this is times when you naturally feel and act like a child, when things remind you of when you were a child. working on this kind of stuff is called doing inner child work, inner child therapy.

if you are not comfortable doing inner child work with your therapist its ok to tell them you are not comfortable, feel its freaking weird. having therapy doesnt require a therapist "getting" you to switch into inner child mode / state of mind. in fact around here it is strickly forbidden for therapists get someone to act like a child by doing inner child work. we believe this is a natural thing that happens and doesnt need any coercing / forcing / getting to happen. the reason we have this rule here where I work is because making a client act like a child can cause the client to have false memories / false inner children / false alternate personalities. We also deal with court cases and the courts will through out any cases where a therapist has caused a client to act like a child, act like they have inner children , act like they have alternate personalities.

again if its freaking weird to you let your therapist know. this kind of therapy work in my opinion and those in the mental health community here should not be done if it makes a client uncomfortable and can be put off until you are more comfortable with yourself and your problems.
