37weeks 4days Anxiety ?

Diana
Yesterday morning, While I was getting ready to go I started getting really hot and my heart racing I had to lay down it was hard to breath and my chest was hurting so bad. I called the doc and he said to go to the hospital.
 All the exams EKG and blood test came out good. So I guess it's anxiety? 
Has this happen to anyone ? 
I am so over being pregnant and really want to meet my son too already. 
I know he won't come until he is ready but I am finding it hard to keep calm and being pregnant. 
I'm due Nov 9 so I have a couple of weeks to go hopefully he is not late 🙏🏼✨
