Body image

Kinda long story... So ever since I hit puberty I've always had people in my family calling me fat or ugly even though I maintained a healthy weight all through high school and into college. Well when we decided to start trying for a baby I put on quite a bit of weight (going from 115lb to 168lb and being 5"4) which I figured going off birth control does that to some people so I thought no big deal. Well my doctor at my first prenatal appointment told me I was still overweight and need to get it under control (now at 145lb) I was kinda shocked how my doctor who I've had since I was 13(now 25yrs old) knowing my history with my body image and How I stuggled with it a lot and still do would say such a thing and be so hurtful!! My boyfriend wants me to get a different doctor now which I kinda agree since now I feel so bad about my body now and my boyfriend has been trying really hard since to make me feel sexy again and how no matter how I look I'll always be sexy to him and it helps but all I can think of is my weight even though to me it doesn't seem like a lot really be affecting my baby's health? Am I really that overweight for my size? How much healthier can I eat when all I can eat is fruit and vegetables since every thing else makes me sick?
