I can't know your full strategy based solely on this post, so correct me if I'm wrong, but it sounds like you're trying to lose weight the two 'classic' ways: going to the gym, and eating 'healthier'. These may be the two things the main character does in a movie during the 'weight loss montage', but they're not as helpful as one might think. Don't get me wrong - the gym is great for many reasons. But changing the 'calories out' part of the equation with exercise is much more difficult that restricting your 'calories in'. To put it in perspective, for me to avoid the calories of a single snickers bar I could a) not eat it in the first place or b) run the longest I've ever run in my life (a few miles). For most people starting out, the level of exercise they are willing to do each day burns a lot fewer calories than it feels like it should. Do not count going up the stairs as a victory. You've burned a half a pretzel's worth of calories. I say that not to be discouraging, but to prevent you from being discourage when you psyche yourself up about something and see no results from it.

Most weight loss happens in the kitchen. Now, the reason I said eating 'healthier' isn't much help is only because, produce marketing is BULLSHIT. I have found so many things with words like 'low fat', 'healthy', 'smart choice', etc that are no better, or are in fact worse, than the generic store brand option. You know those thin weight watchers buns? I almost bought them until I realized the regular (non-thin) stop and shop brand of buns had 10 fewer calories (and costs less!). Your mom's meatballs might be more 'natural' than a bag of cheetoes, but they probably contain a huge amount of calories. Peanuts are healthy, right? Those fuckers might as well be made of pure calories. Movie popcorn is probably far better. Basically, disregard all of the marketing, as well as the conventional wisdom about what is 'healthy'. There are two things you should take into account when you purchase food: the calories, and the satiety. Calories are easy, they're printed on the box (but please please please pay attention to serving sizes! most products have their serving sizes tuned specifically to around 100 calories). Satiety, the ability of a food to make you feel full and satisfied, is more tricky. There are studies out there that rank good based on a 'satiety index' that can easily be found on google, but other than that it's trial and error, and knowing your macros. Protein and fiber are the most filling for me so I try to stick to foods high in those.
