Discouraged about my weight

Any ladies out there that can relate??

I've gained 30 pounds already and I'm only 32 weeks.. I'm just feeling so discouraged about it. My doctor only wants me to gain 35 the whole time and I was dead set on only gaining that but it's so hard. I've got 8 weeks or less and gaining only 5 pounds within that time seems unlikely. I almost cried in the doctors office probably because of simply being emotional but it's still so difficult.

I was overweight to begin with so I just wanted to gain that perfect amount and it's seeming like it's out of reach right now.
