No matter how you feel,
You should know that you are never alone.
Someone somewhere has been through something similar and survived,you can survive too.
If pain gave out a dark colour,the world would be dark. It would be night forever.
But again maybe if pain was written on every face, we would judge people less and accept them as they are. We would help each other and not step on each other. We would carry each others burdens.
Hold on,and as you hold on,be nice to people. Most people are hurting,thats exactly why more people keep getting hurt because as they say "hurt people,hurt people".
