Feeling down

This is my first post here... I'm 6W5 D along and I have 2 older kids that I have to take care of and I feel sick all day long plus it's starting to get to me emotionally as well :( 
I'm down all the time and I lost 10 pounds so far since I can't eat anything at all.... Even plain water tastes bitter and I can't keep it down 
My Dr just put me on zofran but all it's doing is making me drowsy and not focused which terrible if u have other kids to take care of 
With my prior pregnancie it started off like this and then I ended up with a PIC line so I had to go home with it and gave my self bags and bags of IV fluids throughout the day....
I don't want it to get to that point and I don't want to sound like I'm complaining but I am just truly desperate to feel better :((( 
I hate looking at my self in the mirror since I lost so much weight it shows on my face and body I've developed dark circles under my eyes and I look so lifeless :( 
I know it's worth going thru all of this but I'm human and I have no one to talk to about my feelings 😢😢😢
