This is AI, but it resonated with me, particularly the first part, because this is how I feel. It's not that I am afraid to leave the house or because it's painful to go somewhere, but going somewhere seems to be more of a chore than it once was. A simple thing like going to the store to pick something up that I want is likely to be something that I'll put off, put on a list for my wife to pick up on a later date, or order it from Amazon. Something like driving across town to the store seems like a trip. When I have a doctor's appointment, it seems like my whole day is planned around it, although the appointment itself is likely to last only half an hour. I'll feel like I can't plan anything else for that whole day because I have a 10 am doctor's appointment.
