Feel like this pregnancy is killing me.

Na
I just have this huge burden on my chest I need to get out. 
I feel like this pregnancy is actually killing me.
I have high blood pressure now, it's so awful I feel like I am going to explode or have a stroke sometimes. I just stated medication.
My sciatica pain has been so bad that I can't walk or move.
I have SPD and it feels like everything is going to fall out of me sometimes. 
I inexplicably gained 10 pounds which has made the blood pressure worse. 
I'm just laying here, foggy headed from the pressure headache, listening to my quick heartbeat in my ears, throbbing back pain, legs sore from cramping, feeling like I may actually die. Loving my baby to death, but I really hope it doesn't mean literally.
