For my sickness and fear

I’m merlin, 21 years old… I am having a vomiting sensation right after 5 to 6 mouth of my food. Every bite after that was a struggle. Something I vomite too. It happens every meal of the day for almost 1 year. I don’t whether it is sickness or evil spirit. And I also struggling too much with fear. This fear is too much now a days. Please pray for my health and fear. And also for my spiritual connection with God.
