I'm so depressed I feel like just giving up. Maybe I will.


I am just teasing you.
Hang in there! I'm sorry to hear that you have to have surgery. I think it's great that you are thinking about walking after the surgery rather than just sitting around (if it was me, I'd probably be like "I just had surgery, that means I get to eat a tub of ice cream and sit on the couch all day!"). A month may seem like forever right now, but I'm sure it will go by quickly. Once you've recovered, I'm sure you will be able to work up to your usual routine in no time. Look at how much progress you've made already, you're more than halfway to your goal! Even if you can't lose for a month because you can't work out, you have still accomplished something great.
But to give up, look at it in the opposite direction...you're giving up a life over a month. And that can be a HUGE deal.
