well great now I'm off to the ER

I've been awake throwing up since 11 last night. No fever just my body is really sore and I can't keep anything down. So it looks like I'm off to the emergency room. I'm about 90% sure they're going to keep me. Cuz my body has absolutely nothing left can I just keep dry heaving. I pray it's not the flu and that's big for me I don't pray lol. We have adoption court on Wednesday I can't be sick. Wish me luck
