Help! I'm way too fat!

In 2014 I had lost 36lbs and felt pretty darn good. I got engaged to a guy that could eat everything and still be hungry. I slowly started putting all the weight back on. Here it is 2018 and I'm single and I have put every last pound back on. I look horrible and I wouldn't look at myself 2x so why would any guys look at me. I need some advice to get back on the right track again. Any advice would be great. BTW I do not like salad, veggies, or fruit. Artificial sweeteners give me migraines. I know I made it hard, but help!
