It sounds like you're going through a challenging time. I think many on this site have felt some version of what you're feeling about your weight, at least at some point, so you aren't alone in that. Speaking personally, I felt very similar at my high weight - I was extremely uncomfortable and unhappy with how big I was. Nothing fit well, no position felt comfortable, and it made some of my health issues worse.
When you say that nothing is working for you, do you mean that you can't bring yourself to do it for a long time, or that literally no weight is coming off even after a couple months? If it's the former, you may be tracking inaccurately (like with calorie counting, which is common). If it's the latter, you need a doctor's help because that's very unusual and it may be related to a more serious issue.
No matter what you decide to do to lose weight, a couple things may help. It helps to put in effort so you love and appreciate yourself on some level all the time. You don't always have to love everything about yourself, but be kind to yourself. It's harder than it sounds, I know, but even the effort helps a lot.
Also, if you're like me, it will take a good 3 months to really see enough of a difference that you don't feel so uncomfortable. It varies, but that's how long it took me. I didn't even want to start at first because I knew it would take a long while to actually get any results. But they're really worth it later, even when it doesn't feel like it before then. Time will pass anyway, and I know I'll thank myself for losing weight even if it's slower than ideal. Slow loss is still loss.
Not sure if any of this helped, but I hope at least some did. Welcome to the site, by the way!
