I've been a little nervous lately and I don't know why exactly.
Nervous? That's interesting. Has anything changed recently? What are your thoughts on why it's happening?
I'm really not sure, it's just a general type of thing.
I see. I'm sorry you're having trouble with that. Have you thought about therapy? Maybe your health insurance will cover a free consultation or something. Or perhaps you just need a simple routine change, with some exercise and more time outside. I hope you find the answer, whatever it is.
