I keep gaining weight and I have less and less clothes🐷🫢

I've gained a lot of weight, and my swimsuit is getting too small for me. I try to put on some old jeans but it's no surprise that they barely fit, that's how I notice my belly has a lot of fat, My legs are huge, it's taking me a lot of work to close these pants, you can notice it in my breathing and my sweat, in the end will I have to wear pajamas all the time?
