How I manage my mental health

Everybody has mental health. The question is how good it is, and how we manage it. We need strategies for managing our emotions and feelings. Here’s how.

Feeling Unreal: depersonalisation / derealisation disorder

‘I don’t feel real. All the time—literally all the time—I feel like I’m living life from behind a glass screen, or that I’m watching life as it’s happening on TV but it’s not real. I’m always ten yards removed from it. I don’t cry. I don’t feel things. I feel like I’m in a dream. I feel like I’m going mad. Even now, talking to you, I’m not sure if this is really happening or not or if I’m just imagining it. The GP says I’m just depressed, but I’m not.’

Carolyn Spring explains this concept she developed based on Stephen Porges’ polyvagal therory.
