Is it a health issue??

When you experience stress or have something to worry about
My heart hurts, and the feeling of tightness is just too overwhelmingㅠㅠ

In times like this, I just want to do nothing and restㅠ
Is it because I'm sensitive?
Or maybe it's a disease, I feel like something's strange.
Should I go to the hospital and get a check-up?
Will I get better if I exercise?
I'm wondering if there is a health issue!
