Ohh yes but it can also be just in your head. That same thing happened to me, I was on a cruise once and meet this amazing guy. Whenever I wasnt with him on the boat I felt extremly light headed and always felt like throwing up. I hardly ate and couldnt sleep.
You just have to let it pass, try to stop thinking about him and meet a new guy that lives near youu.
I hope you feel better hunn
Yes because you emotions tie into your physical health that's why you see people wit lots of anger issues or heartbreak they get sick and some even get. Diseases and then the worst case is they can die ....yes you can die from a broken heart!
