Hate my stomach

So I’ve gained about 25 pounds. Usually I stay around 145 and during the summer I somehow managed to get myself to 170 😒 Even now In April, I am still 170. I LOVE my ass, it’s huge and my breasts seem to have grown which is also good as I was barely a B cup.. but my stomach is horrid. I look pregnant. The kids at work ask me all the time if I’m pregnant and some of them try to grab my stomach. Im supposed to go to an indoor water park on Friday and I can’t imagine me in a bathing suit. But I’m also extremely disinterested in working out. I have no idea what to do. Thinking of starving myself honestly 😒 but then I’d have no butt….
