Trying to bounce back from surgery.

I was doing really well at working out by doing T25 videos and tracking. Then I started to feel crappy and turned to comfort food and put back on the 20lbs I lost previously. Turns out the crappy feeling was from a growing fibroid. After 3 months of suffering I found out the problem and shortly after had a hysterectomy. Now I am 6 weeks post hyst and looking to ease back into my workouts. Last week I started walking more and am slowly increasing my activity. But have not done a whole lot since October and am feeling the pains. I have a long road a head to drop the weight. After surgery I went back to tracking my food and have lost 16lbs; it was easier now that I felt better internally and was craving healthier options instead of comfort food. Now I need to drop 40lbs more and hit my goal.
