I feel deceived...

I want to be clear, I am very happy that my husband and I are expecting our first child; however, I feel annoyed with being pregnant. All over social media I've seen nothing but posts from pregnant women screaming from the rooftops about how beautiful and amazing and wonderful pregnancy is. I feel terrible ALL THE TIME, and I am extremely tired. And I am getting fat because all I do is eat all day long to try to get rid of the nauseous feeling. And I am only 7w6d, so the amount of weight I have gained is far more than normal. I was an active person before I got pregnant. I run marathons. And I try to make myself walk outside or on the treadmill every day, but even half a mile feels like torture. And then on top of it all, I am so nervous that I'll miscarry, and with how miserable I feel, I'm not sure I could willingly enter into this again without having the baby as the end result. Those who do know I'm pregnant and struggling keep saying, "it will be worth it in the end!" I want to punch them in the face when they say that. Duh! I know that having a child with my husband would be life alteringly amazing. Why do you think we are doing this? And I'm a teacher. I LOVE kids. I WANT kids. This is just not fun at all, and I feel like nobody ever tells you it's going to suck. Maybe I'm overly emotional with all these hormones, but it's just not the picture that society has painted.
