I'm really sick .. Really sick. 6 months pregnant with #3 , have a 3 year old (almost)& an 8 month old.. I have bronchopneumonia & my head is killing me, I also have pink eye and my nose is a faucet (if it's not snot its blood):/ anyways I have been like this for days and incapable of doing anything! I have to force myself to do anything!! I have to force myself to make supper for the kids , I have to force myself to get up to go to the loo, I have to force myself to wake up in the mornings. My fiancé works out of town and won't come home to help although I know he can.he blows off my sickness as well as his mother . My family lives 28 hours away otherwise they would help and I've asked my in laws and sisters in law and I was refused. My MIL  (before I found out I had bronchopneumonia) actually came over a few days ago to watch my oldest kid so I can go get me and baby checked out, she tried to stop me from going and said"I'll pick you up some flu medicine and you can just tend to the girls" I don't think that bitch really knew how sick I am.. Point is my fiances side of the family doesn't give a shit.. My family DOES but they're too far .. I can't have a day off to recover .. So what do I do.. I'm just about ready to die.
Update and add on: I wake up panicking to breathe at night and suffer all day from coughing fits and breathing incapabilities .. No matter how much I beg for help from SO family, they make up an excuse.
Update; I wound up breaking a rib from coughing too much & my in laws still don't care. My mom came down to help and take my three year old and I am feeling better . Thank goodness for my momma
