I used to get this real bad. Couldn’t leave the flat most days. I’d have my coat and shoes on, and would keep approaching the door and just couldnt leave. Sometimes I’d think I could hear footsteps in the hallway, and would have to wait by the peephole for a couple of minutes, then lose my nerve and go back to work up the courage to approach the door again. Just unable to open the door and break the seal between safety and exposure.

Seek help if you have the option. It doesnt get better on its own.
