You can do this! Two years ago going shopping at the grocery store wore me out. My job was robbing me of mobility and because of that family time and activities. I'm not 100%, but I can go for 2 mile walks now, ride bikes, and shop (although that's not always a good thing ;). I can't wait to see where I am in 2013 and when you look back, you're going to be so proud of yourself!
