I think it would depend on what I was being treated for. I don't know that therapists share their personal notes with the client, just the HIPPA-required ones used for insurance. I don't think the personal thearpy notes would be of much use to me to give a new person even if one could get them but if I were on meds, used insurance, and/or had been hospitalized, I might get and give those to a new T AND discuss them with them.
