It’s feeling hopeless

I need help. I’m overweight borderline obese by BMI standards. I feel like I’ve tried everything, but it never works because I can’t stick to it. I hate the way I think of food. I eat super fast, and always eat my whole meal (habit from childhood). I’m so tired of feeling this way. I have a solid 50lbs to lose to be healthy. I need any and all advice and tips. I’ve been considering a gym again and that maybe I’d stick to it if I joined a group workout? I was running two miles daily which I loved, but my hip started aching super bad every time I ran, so I have to rest it now for at least a month. I just feel so depressed over this. I want to feel good again. Physically, mentally, emotionally. Anyways, thanks for reading. Seriously leave all tips below, I can use them! Thanks!
