This is me too! I have completely shut off from the outside world and feel too exhausted to do anything about it. I think once you get into the habit of not socializing it is very nerve-wracking and difficult to break. I nearly died in December and now am living in fear I won't wake up again every morning so my anxiety is crazy. Thankfully I do have one AMAZING friend who I met at a parent and baby group when we had our first bubbas 11 years ago. Without her I don't know where I would be. Sometimes having one constant friend is better than a lot of acquaintances.
