does anyone else feel like this?

my hubby and I were ttc 8 months before we got our BFP. I'm 6 weeks and MISERABLE. Before I was pregnant, I thought I had everything sorted out, like where I wanted to deliver and what crib I wanted. Now I can't make up my mind and I feel so completely unprepared. I feel terrible that I'm not enjoying my pregnancy, but it's so stressful and I just feel like crap. I'm bloated and tired and freaking out about everything.
