Comfort Partner

I studied myself lately in the mirror and felt a little discourage of what i see. I gained some weight and i think a lot. I felt different this past month, I'm exhausted most of the time and some of my clothes won't fit me anymore. Honestly, i can't help it, food is very comforting and I'm craving to eat most of the time. I know i have to do something about this just based of what i feel like the exhausting and my belly is getting big. I need some exercises too i know...
