I just don’t know anymore....

I’m 8 weeks today and lately it feels like my world is falling apart. I’m so tired and crampy and all I want to do is cry and sleep. I have no appetite and I feel like I’m going to throw up all the time. I hate everything and every one. Why do I feel like this when everyone else I know who is pregnant has this glow and is all happiness and sunshine? I just don’t get it!
