I cried last night

As
I haven't had much in way of emotional episodes this pregnancy. But last night there was this cricket right over my head outside the window that was chirping. I finally tuned it out and fell asleep at 2 and my toddler woke up. Cuddled him half an hour and put him back to bed. My SO comes back in the room and touches my back and I just explode into tears. I am SO tired. I haven't slept for more than an hour, soundly, in over a month. I can take Tylenol pm, but then I have screwed up dreams. I am absolutely dying. 
And to anyone who's had someone say "you think you aren't sleeping now wait until baby is born" fuck them, they can shut the hell up. As a second time mom I can tell you that it IS better. No pelvic girdle pain, no acid reflux, no Charlie horses, no 15 minutes to turn over, no nausea, no constantly peeing. Just waking up to feed baby, which if you're breast feeding, will put you both to sleep! Yeah that's right. Breast feeding makes you tired in the beginning. So maybe it's 2 hour blocks, but it's two hour blocks of REAL sleep. And I am so, so ready. If I don't get rest soon I don't know how I'm going to get through labor.
