Know how heartbreak feels like?

The moment when you know that your heart just got broken. It's not related to anything that just happened, just memories of the past. When I see the two of you together, it's like my heart just felt so heavy. Just a deep gloom and its a feeling that comes close to the worst I have ever felt thus far. Hearing you talk about your past experiences with him brought back that exact same feeling. All I can do is just look down and hope the feeling goes away soon. I should stop living in the past otherwise my heart will be permanently broken! It's more then sad and no words can do it justice. Heartbreak is a bad, bad thing to experience....
