No, windseeker you are not alone in this! I know I would rather be in a cast or have some other injury that people could see so that they would understand that I need to rest, or so they would even offer to help. But we don't. We have this thing that is frustrating, painful and sometimes lonely injury.
But know that even though today may have been horrible, you will have one of those days soon where you don't hurt so much, or are able to function just a little easier. Those are the days that give me hope and peace in my heart that I can do this.
