I'm sorry you are feeling badly today. Can you talk to a therapist about this?
I have felt this on and off since I was in high school....I'm 42. Sometimes I will have a whole day feeling hazy, sometimes I will feel it acutely for 30 seconds at random times during the day. Lately, for the past year, its been an overall haze of it all day every day with momentary glimpses of my true self. awful.
