Overweight little...help

I’ve started some depression and anxiety meds and it’s helped a little not completely but I feel much better. But I’ve gotten to the BIGGEST I have ever been. I’ve always wanted to weight 130/140 but I’m 260!!!!!! We are going on a cruise in 1 year 5 months. I want to loose a lot of weight but I don’t want saggy skin. How do I do this?

He loves my big boobs but wants my belly to be smaller and my butt to be bigger. (All things I like and want). How do y’all “reward” yourself in little/sub space? Daddy needs more help too he’s new to being a daddy and it’s being wonderful at it. We need punishments for not working out or cleaning the house and rewards as well.
