As far as maladaptive daydreaming goes, I've done it almost as long as I can remember without ever knowing what it was called. I was also pretty isolated in I was the only one with my own personal fantasy world, but it was my therapist who helped me define it. She gave me resources and sites alike, among them Daydream In Blue. It feels incredible finally being able to feel like I'm not crazy, and it's even better knowing I can connect with people who may have some similar experiences.
I found the term Maladaptive Daydreaming very recently, and knew right away it was me. At 59 years old I have lost so much time just stuck in my head. I have now found this community and want to find a therapist that can help. I don’t want to just live out the rest of my life like this.
