Weight gain guilt

I am 5'2" and lost 30 lbs to get down to 135 last year (it works for my body shape). I was thrilled. From then until I got pregnant, I put on around 25 lbs and started my pregnancy at 159. At 10 weeks I'm at 164. I feel massive, I feel guilty for gaining weight, and because of my constant nausea and food aversions, all I want to eat is relatively unhealthy things. I feel like I'm not doing right for the baby by gaining the weight before getting pregnant and now I'm not even eating right for the baby. I also worry that I'll never lose the weight. I have a lot of body image issues (in case you couldn't tell) and I'm really struggling right now. I feel hideous. And the pregnancy mustache, beard, and acne aren't helping, but that's a different post...
