On and off I have gone through extended periods of feeling like I am not connected to the world. Like I am moving in it but not a part of it. When I am this way I feel emotionless, sometimes like I am floating. I used to change my situation when I got this way. I would go to the beach or to the gym. Sometimes I would call someone just to try to feel connected. I have had this as far back as I can remember. Sense getting into therapy I have learned that these are dissociative, derealization and depersonalizationepisodes. Now, when I am able to remember, I use ice or something else to ground myself. I also think my anxiety medication helps me to be more receptive to grounding. When I ground myself I feel a fog disperse from around me and suddenly my feet are back on the ground. I feel fearful but connected. Maybe you need to learn more grounding techniques. Maybe that will help.
