Up 40lbs

I am so upset i am up to 335 lbs .When I had my surgery in my weight was 477 I got down to 296. But with two deaths of babies and a terrible love life. I have blown up to 335 lbs . A ll I do is eat and I dont know what to do to get my weight back down. I can eat anything like I have never had the surgery. It scares me that I will over grow again help help help
