Anybody miserable?

I'm 16w3d and I feel like I haven't been able to enjoy a single moment of this pregnancy because I'm constantly miserable. I feel bloated 90% of the time, and when I'm not feeling like there is just a huge gas bubble pushing all of my organs out of place, I have nausea, heartburn, and am exhausted. Am I alone? I feel like I'm just being ungrateful, but I just can't enjoy this when I feel so terrible.
