No one prepares you for how bad morning sickness can be

I am absolutely miserable. Been wanting to stay on the couch every second. it was a miracle for me to go out one day but I couldn't take it. felt terrible and puked on the car ride home. ran to my couch. Nothing helps:(((( I'm 6 weeks and a few days. I've been living on the couch for a week but it seems like eternity. I feel like no one prepares you for this!! I've heard that oh it's just morning sickness. it subsides and you go about your day. No, not me. I just feel so alone and I don't know how much longer I can bare. this is hell. I don't want to eat anything. I'm barely drinking. this isn't healthy. and my husband poor thing doesn't know what to do and is worried about me. I feel warm but luckily no fever. I am able to keep food and liquids down but today I did throw up a little bit of a juice I drank. this past week I was just dry heaving. Now I'm scared I won't keep things down. I'm just so scared I will have this the whole pregnancy. I always wanted a big family and felt it was my calling to be a mom but I can't imagine going through this again especially with a kid to take care of..any positive thoughts please. I just needed to let it out :(
