Terrified

I am terrified that this is going to last through the whole pregnancy. Yes, medication helps, but barely and definitely not enough to allow me to have regular meals. I recently ran out of medicine, apparently the nice nurse at the clinic couldn't get my prescription refilled, and last night from 4pm-11am I was puking up nothing but stomach acid. Jacob walked to WalGreen's at 9am to get the expensive prescription filled ($60 for 10 doses) and I've stopped vomiting, but I still feel like I will again at any second. The scariest thing is that when its this bad it can last through the whole pregnancy- something I don't know how to survive. I keep telling myself, "just a few more weeks, just a couple more weeks," but after last night I am really doubtful. I need lots of prayers because I've never been more scared in my entire life.
