TW: weight gain

I’m very early pregnant with my second. I gained 45 pounds with my first and did not really lose any weight after having my first. Only about 20 pounds but have gained 10 over the last year. My first is about to turn one. I am spiraling and obsessing over gaining excessive weight with this second pregnancy and being extremely heavy after this baby 😭 I’m going to the gym 4-5 times a week and trying to eat healthy but I don’t know what else to do. Has anyone else been through something similar? Any advice?
