How do you handle the anniversary of becoming disabled?

How do you handle the anniversary of becoming disabled if it's a specific day you can pin point? I would like to forget the date and ignore it entirely but I ended up with injuries due to childbirth. To make it worse I had my baby the day after my own birthday. So as that day approaches again I have a hard time handling it because I know exactly how long I've been having to deal with it and the longer it goes I wonder if what I hoped would be temporary is going to be permanent. I'm also reminded I'm another year older and it's been another year of being extremely limited and in immense pain. But I have to try to be happy and plan a party instead.
