I'd recommend trying daily meditation for a couple weeks, see if it helps you. Otherwise check in with your doctor, you could have anxiety. It's normal to have these feelings every now and then. It's not normal to feel like that all the time.
And, perhaps a chat with your doctor is a good idea in any event.
Good for you for thinking how to work for the better.
It just feels more realistic, more pragmatic. More grounded in how the world actually is. I really like it.
