Thanks, futuremama. I work from home right now. I finished my degree before writing any of my papers to get me out of the lab as fast as possible, so I'm having to split my time as a SAHM and then write the last of my research papers at home when DS is having downtime and I can focus on the technical writing.
It's not really sadness or anxiety so much, though the pregnancy is definitely making me more teary than I'm used to. It's more like inertia once I'm down and having trouble keeping moving once I start to do something. I'll need to cook DS some lunch and I'll have been sitting on the floor with him and it'll take a good 10 minutes of convincing myself that "no, really, you have to get up and cook. No one is going to do it if you don't. If you just stand up, you'll be able to do it. Just stand up. stand up. stand up." because standing up once I've been still just seems gargantuan. I'll be painting house trim and I'll just put the brush down and not be able to do it anymore and I'll be stuck completely unable to finish any part of the task (cleaning the brush, closing the paint can) because it suddenly seems an impossible amount of work. I tried carrying old torn up cushions from the storage shed to the back of the pick-up truck to take to the dump and got halfway with one cushion and had to just sit down on the cushion and watch DS play in the backyard and I just couldn't bring myself to even finish taking that one cushion to the truck so it was still sitting in the middle of the yard when DH got home. There's been a pile of books sitting in the living room floor for a week because I just don't have the inspiration to move them 10 feet to the bookshelf. I just feel crippled, like part of me isn't working. Even loading the washer, putting soap in, and pushing the button is like "Man, I really don't know if I can manage all of that."
We go somewhere every day, but once we're there, it's a fight for me to pull myself together and load us back in the car to go home instead of just calling DH for help and just sitting there not moving. It almost feels like some kind of mineral deficiency, but my diet is good, way better than the average person, and I take prenatals and several other supplements (b12, iron, Mg, Ca, VitD) I took up when I was still bf during the pregnancy.
