Weight gain is hard!!

Just entered my 3rd trimester. I am extremely depressed about my weight gain. I gained 6 lbs month 4, 8 lbs month 5 and probably close to 6 month 6. I am so depressed over it. I don’t want to go my OB appt on Tuesday Bc I don’t want to see how much I weigh, and I don’t want my Dr to say anything (it shouldn’t be more than 4 a month). I also don’t want to do my maternity shoot anymore. No one understands how sad it makes me. My face is fat. My arms are fat. I was around 135 and now I’m like 156. This is REALLY hard!
