An emotional poem, no doubt, and I hope someday that the tears won't always mean loss, whether loss of memories or moments of joy. That the tears won't always symbolize the past and wanting to forget or that chaotic in between when moving on from something or someone.
Tears are tricky that way, because it's not always black and white, and often bittersweet instead. You captured that well here.
Yes, a very sad piece indeed and the repetition made it sound like an uncontrollable cry which just doesn't stop. Well written and I hope this has helped you trying to get it all out and hopefully moving on to higher grounds.
