Weight gain after birth of my first, 11 months ago.

I was ok with my weight durimg my first pregnancy, I lost 11 pounds & my last weight in at drs then was 298. Fast forward about 11 months & I'm at 324. 4 weeks later I gained 2 pounds, which I know is ok, but I'm so disgusted with myself right now with my weight. I've never been this heavy & have no plans on gaining anymore!! My husband & his sister is a bad influence when it comes to eating away from home, he always wants some kind of fast food (the thought of fast food make a me sick). But most the time I will just go with it cause I have been craving root beer, yes I know that alone will cause unnecessary weight gain alone. But I got my root beer with my first, just not with the fast food & didn't gain.. I'm just so lost, I eat fruit, veggies & drink water at home & try not to eat every time I feel hungry, which seems to be all the time. Anyone have any advice on how to help curve hunger? I try so hard to eat healthy but it's so hard with those around me.. I'm 19w1d💕
