Weight gain

Was so proud because I quit smoking 2 years ago and now ,I'm upset because  now I seem to be binge eating  and can't seem to stop, wondering if after 5 years of loosing my spouse, if it's lonelyness, I thought I was handeling and realizing I'n not doing so well after  all. I don't feel depressed , I have lots of friends and don't do it when I go out ,Just here at home. I could use some support.
