Is it normal for me to freak out so much?

Hormones suck!!! They are evil!! BUT you are totally normal!! Don't worry hun, you are going to be a great mommy! Take a deep breath and relax! Doesn't sound like you have done anything to harm your baby on purpose! No one is perfect, all you can do is the best you can do :) Enjoy the last couple of week of your pregnancy and congrats :)
