Throwing a tantrum

I've been having a tough time with my pregnancy it's my first baby and I'm 11 weeks right now. I feel sick all the time and especially right now I just feel so sick and throwing up. I feel like everything I eat it's just horrible for me even with my prenatal vitamins. I try not to complain because I'm sure a lot of women go through a tougher time. Do you guys ever feel like you don't wanna do this anymore because of throwing up and feeling sick all the time. I feel bad saying it because it's my precious baby but it's just hard adjusting to all this and it just takes a toll on you.
