Easily discouraged

This was week 2 of the walking challenge with my sister. Ever since my shoes were stolen last week, I have been feeling very discouraged about exercise. This week I got in my miles, but it was rough! We went to Disneyland and the zoo this week and we went out of our way to walk more than usual so I could get my miles in! On Thursday I decided to walk on my lunch break and I took off for a fast 2 mile walk...IN FLIP FLOPS! So dumb. I thought they would feel better than the shoes that make my toes numb. Bad idea. I think I have plantar fasciitis. When I walk more than a few steps, I get a sharp pain in my heel that heads up to my calf. It feels awesome... Today I needed to get in my last mile so I got on the treadmill and walked like a gimp! It took me 23 minutes to do a mile! Suck! So according to about.com I need to rest my foot for a few days and get some better shoes and maybe try some heel seats/cups. Sounds like a plan :)
