Most people don't realize what they have until its gone but now it's too late so their heart plays a sad song.They didn't know the emotions they had were so strong because they tried to hide them or deny them because the feelings felt wrong.
But the emotions were real and they wont go away. Now you feel alone and the pain grows stonger each day, but you can't fix this because you just waited to late. So you have to take it as a lesson learned and fight through the pain.
I once spoke to a man that was on his death bed he told me of his life all his prides and regrets, I heard all his stories and he gave me the best advice I could get. He said life is too short to be full of regrets and happiness is rare so don't be scared to grab it because those are the memories you'll never forget and in the blink of an eye it's over your dead.
The moral of the story is don't wait until the last minute to open your eyes, you'll see beauty and pain and have emotions of all kind. But don't wait until the last minute to accept these things in your life because life really has a last minute and when its over you die
