Sickness

Last night I always I felt sick. However I did end up nearly being sick which hasn't happened. I've barely slept and I always feel like I need a way to take my mind off of it. I couldn't sleep after because I was worried it would happen again and I was on my own. My mom ended up sleeping next to me as we were both tired and it was now about 12:30 in the morning. I slept fully through the night however I did wake up a bit earlier thank I usually do. I'm not sure if it's anxiety maybe I'm just ill or have eaten something bad but I've been feeling like it for a while so would say it's anxiety based. I have no clue what to do and how to get it away.
