Burning

I seem to be on fire. I'm burning through all my relationships, disintegrating warmth with a wall of white heat. Leaving clusters of ashes where friendships used to be. They turn to powder when I touch them; they blow away in the wind. Even the faintest of each air current scatters the pulverized remains; I try to catch them (I know cannot put them back together; one cannot unburn ash, but I wanted to place them in a pretty urn on the mantelpiece) but they are gone.

This is a tricky sort of fire. It feels warm as always to me.... I didn't know I was on fire until my loved ones screamed and showed me their burns. How do I stop? What have I done?
