I have to admit I'm going through this a little. I'd be a lot better if I didn't have to work, because it's utterly exhausting to get through my days at work. Normally, I'd hate a sit down job, but right now I'd embrace it. I am a nurse with 12 hour shifts(which are glorious when not pregnant). I'm just so tired.
Part of me just wants to tell myself to stop feeling this way, the only thing that remotely helps(only a little) is that I am pretty darn sure this is my last one so I won't experience this again so I should try to embrace the good parts. Only helps a little though.
I miss being in shape, going for a run, not getting irritated when my 9 year old dd snuggles(right now, it's like "get away! I'm uncomfortable!"), being able to comfortably pick something off the floor, etc...
