I want to lose weight but I can’t

I’m 18 and I am 5’10 tall and I weigh 190 pounds unfortunately I can’t exercise for quite a long time and I’m not exercising right now. At the start of this year I was 179 pounds but my weight gradually increased due to my binge eating behaviour. I even tried tried fasting and keto diets but none of those diets were worked out for me. I got demotivated quite a lot. But I want to make a comeback and lose that excess 11 pounds. But I am always asking to my self that “Am I a hopeless case” because of my eating habits. I get most of my nutrition from fast food and junk food. A month ago I quit smoking and I want to stop eating junk food in order to maintain my health. Do you guys have any advice for me in order to solve this problem?
