I'm miserable

My morning sickness has landed me in the ER for a second time this week. I'm down 7lbs in 6 days. I woke up and vomited 4 times by 10am today. Can't keep fluids down and have a massive headache. I wanted nothing more than to enjoy this pregnancy as it's my first but I feel like I'm going through hell. No one I talk to has had morning sickness this bad so it's hard to relate to anyone. People keep telling me, take this, eat that, drink this. Well I do! I throw it all up. I just want to crawl in a hole right now. Sorry for ranting but not all pregnancies have you glowing. Ugh.
