Is this normal??? I'm very scared!!

Meagan • I am happily married to my husband.
Every time I eat or drink something I vomit it back up! I am 8 weeks pregnant if these week by week <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby apps</a> is accurate. I done been to the hospital last Monday for vomiting non stop. I hope all of this is normal because I'm so scared something is wrong! I do have anxiety which i keep thinking about negative stuff. This is my first pregnancy and just want everything to go smoothly. I have heard so much horrors about pregnant women it just makes me wanna cry especially the c section part.
