I hate my scale.

I hate my scale. I haven't stepped on it in months, but today I was feeling good about my looks and thought I would just check... 13 months post partem and I thought I would weigh less than I do. I started my pregnancy Spring of 2017 weighing about 150 pounds. I only gained 17 pounds during my pregnancy, by some miracle, and had a healthy 7 pound 7 ounce baby. Post partem I dropped pretty quickly back down to 155 and I have been stuck there. I weighed 159 today. I am usually pretty happy with how I look but I let that stupid number make me a little unhappy. I have so much to be thankful for and I shouldn't be too hard on myself I guess. I was never able to breastfeed, but my baby is healthy and growing. I never make time to work out since I work 12 hour shifts all week and just want my spare time with my baby. I need to focus on the positive. Does anyone else struggle with this?
