Feeling like an early failure...

Cat
Before I got pregnant I was certain I would be so good in pregnancy - eat well, the best prenatals, lots of exercise... But now 7.5 weeks in, I'm sick all the time, eating terribly because everything makes me sick , and barely able to go to work and home, passing out after dinner. Gummy prenatals are all I can stomach. My house is a mess. I feel like such a failure and it's still so early... Please tell me someone else is struggling too- all I hear are ppl eating well and exercising and I can't help but be so Jealous!
