Feeling down

Not only do I not feel fast anymore I stand in the closet all morning trying to find clothes that don't hug the fat roll. I don't know what is different but something is bc I run and run but I just keep gaining weight in my legs and belly. Now i haven't gotten into a full routine yet with JM so I know I could do better there. But what has changed in the past year that has caused the weight gain to begin with? I look at my lunches, still packing the same thing. I look at our dinners, still pretty much the same thing. My runs actually have increased in distance and frequency but nothing! Just not feeling good today.....
