Weight gain anxiety

I'm starting to feel really conscious of my body.

I know I'm pregnant and I've only gained 10lb (5kg) at 25 weeks 3 days which is actually not bad but I can't help but feel fat and ugly. I'm struggling to eat because I see everything as making me fat and then it makes me feel sick.

I gained a lot of weight in my first pregnancy and managed to lose it all within a year so I'm not sure why I'm so paranoid. I don't know what's going on in my head.

Is this normal??
