Worried about weight during pregnancy

Hi mothers to be. I'm almost 11 weeks and I've already put on 11 pounds. I've been feeling extremely unwell for the whole time, especially every 3 hours if I don't eat something. I'm naturally curvy, size 10. I'm really feeling guilty especially since my whole family Including my husband seem super worried about my weight. I'm really hungry, and I feel sick if I don't eat something. I'm attracted to cheese toasts, I could eat them all day. And all food in general but healthy choices (salads, fruits, boiled veggies). So I've been feeling anxious, and sad, and crying. I feel a lot of pressure which makes me feel worse. Any help? Thank you!
