You know you're heartbroken when...You have an actual pain in your chest when you think about the past and realize that its all gone.
You'll never have another one of those moments with that person again.
You would rather live in pain for the rest of your life than allow yourself to love someone else.
Hope becomes its own bodily reaction, reproduces to fill in cracks of your heart after every encounter you have with that person, and nothing happens.
Even just after talking to them for two minutes over nothing makes you want to cry because all you really want to be able to say is "I miss you" but you can't because it would make things worse.
Nobody can compare with that person, so you dont date.
You'd consider changing around your schedule so you could "run into" that person when you just so happen to know they'll be on their way home. Its not stalking. It's creating opportunities.
All those feelings you had when you first started to fall for them, the fluttering in your chest, the falling stomach feeling, the constant thinking of little things that are probably insignificant, it all comes back and is full fledged.
The idea of finding out they love someone else is enough to make you want to hide away for the rest of you life just so you don't run the risk of seeing them together.
You have to fight off the instinct to hold their hand or kiss them the way you used to, and it takes effort.
You become weird and akward in their presence often because you cant just be yourself, they already know you and they'll be able to anticipate what youre going to say or do.
If you wanted to say "I love you" , they would see it coming and would themselves become akward too. They would likely try to cut you off before you got the chance to say it.
You feel numb inside after awhile of not seeing or talking to them. You mistake it for being over them and then you run into them and immediately realize just how wrong you were.
There are so many different symptoms of a broken heart. This is just what I know for myself. Im sure I'll find out the rest later.
