feel like giving up

I sometimes wonder why I am doing this and then remember it is for my health.  So many days pass when I just don't feel good that I just don't care any longer about what happens.  I know that is the depression talking to me and not everything else but it just gets so darn hard to keep your chin up when every day is full of hardship.  Then of course to make matters worse I ended up getting into a wreck with my car.  I got hurt a little because it jarred my back really bad but it was more being shaken up than anything.  I have under three months left for the six month wait and then off to approval and then surgery.  I know that after surgery I will have a few weeks where I will be not feeling up to par but my hope is that once I can get healed from the surgery and pass all that things will look up.  I just get tired of not feeling well and I know it will get better.  I've started doing things that I haven't done before and that is dare to dream about a thinner more active me.
