I HATE my pregnant body

I feel horrible about how I look. I started out my pregnancy at just 107 pounds at 5'6. I was underweight but thats just how I've always naturally been. I've always fit into size 1 things without a problem and have been very confident in my body... until now. I'm 26 weeks and I've already gained about 30 pounds. My entire butt, thighs, and boobs are COVERED in deep and dark stretch marks. I feel fat and I look like a 2 year old used a purple marker all over my body. I just feel so down about myself. The thing is, its all my fault that I've gained so much weight. My appetite has SIGNIFICANTLY increased from how it usually is and I find myself eating 6 or 7 full sized meals a day. I cant seem to stop eating. Its just making all of these problems so much worse. I don't know what to do. I love my little boy more than anything and I know it'll be worth it but I'm just feeling so down in my body right now. Is anyone else feeling this way?
