falling really fast

Today has been hell.  I have a really really severe phobia of throwing up and my little brother threw up today due to a stomach bug.  I have spent time with him and stuff and all day i have just been pacing around and im like scared to move and i cant eat and i like really dont know what to do.  I dont even know if I have a question I just am so upset.  All I have been doing all day is crying so hard because I dont know what to do.  I cant throw up...i cant...i would rather kill myself any second than to throw up.  I'm so scared im gonna catch this bug and i feel like I cant escape it.  I cant go around my parents or anything cause theyve been around my brother who is throwing up.  I cant go in any rooms he's been in in the past few days (which is every room except mine).  
I'm thinking about how I have to go to school tomorrow and I just cant handle it all.  Im going to be thinking of throwing up the whole day and i cant escape it.  My best friend who is the only one who knows how bad this is for me broke up with me....and now i feel like i have no one who will listen to me or calm me, because my mom just screams at me when I freak out an it makes it all worse.

I feel like its literally the end of the world.  I have no idea how I'm going to make it through the night.  And not only do i have seriously horrible anxiety, but Im super depressed becuase i have been doing so well with not getting anxiety...but now its all shot to hell.  I cant throw up.....i dont know wat to do....i just want to die becuase thats better than feeling as terrified as this.

First off, take a deep breath.

Now, I've fortunately never suffered from emetophobia, but I know that any type of anxiety requires you to relax.

Be hopeful that you will not catch the bug your brother has. How's your immune system? Did you know anxiety can actually lower your immune system?

Do not do anything to harm yourself. Like I said before, you might not catch the bug if you stay away from your brother. Wash your hand often, cover your mouth and nose if you're around anything that could be contaminated, and most importantly get some good rest.

I wish you well.
