Hi.Welcome.

How is your psychologist helping you with this?Have you been delving into what's behind all the fear that's causing this?Have you been diagnosed with anything?Do you have PTSD or a dissociative disorder?

I used to sleepwalk very often,not to the extreme you do,but I did leave my home.Sometimes I wasn't sure if I had just dreamt I had gone places or if it really happened.I would wake up with mud or dirt on my feet which made me believe I really was.

I have PTSD and once I started working on past traumas the sleepwalking stopped after doing it since childhood.I'm not really sure if it was really sleepwalking or more of a dissociative thing ,but either way,therapy helped.

Do you know what's behind your fear?
