Survival mode still

I’m 19.3 with our third baby. I was sick 24/7 until birth with the other two so not sure why I hoped this pregnancy would be any different… but I’m miserably nauseous 24/7 still but this week has been horrifically worse. I just want to feel better, be able to eat better (literally in survival mode of eat whatever makes the nausea less/not worse). I’m just so tired of feeling this way. I’m tired of driving heaving on my way to work/home/in my office. Dreading meal times but have to cook since I have two other kiddos. Sigh. Sorry , just needed to vent.
