Pregnant n depressed

Hey. So I'm 13 weeks and I'm jus feeling really down. When we found out I was pregnant, we were very excited but now I'm just going through soooo much. I can't hold anything down. It's hard for me to eat. Fruits. Soup. Meats. I'm jus always puking it back up. I can't find anything the baby will take down. I'm having horrible morning sickness and heart burn. 😓😭😭 I jus wanna cry because I just can't have a good day or night. My morning sickness comes through my mouth n nose n feels like I'm choking. It hurts sooo bad. Is it supposed to be like this?? I'm due nov 14. N I've never been more anxious to have this baby.
