Sometimes it's not the pain that you suffer, it's your negative thoughts that makes things seem worst.
Sometimes we get too possesive with someone we don't even own.It's a side effect of loving too much, and receiving too little..
Sometimes, we waste too much time thinking about someone who doesn't even think about us for a second.
And sometimes, we say "I just want you to be happy", but deep in our heart we know, we still want to be their happiness. :/
