Why do we always run from it, that physical and mental darkness? Whenever it comes we flee from it. Too scared to approach it. Often times it exposes our many failures, which we don't like since it pulls us down from our little high and makes us face reality. Facing that reality is something that none of us want to do, but it's something we have to do. We have to face that darkness or we'll spend the rest of our lives running from it and the more we run from it the more it takes us over. Alcoholism, drug addiction, porn addiction, it all begins with running from the darkness.
We're too blind to see the simple beauty of being in that darkness. Finding your way through that darkness. Spotting the light at the end and fighting towards it. The world just opens up in front of you. The possibilities become endless. Life becomes worthwhile, it's no longer dull. Fear just becomes irrelevant, it no longer has control over you. The little things in life become more apparent and beautiful. The beauty isn't becoming like the darkness. It is striving for better in that darkness. Fighting forward when you have every reason to quit. That is the beauty of it.
If you can't find the light then set yourself on fire.Be the light you need so you can find your way home and you might guide someone else home as well. Every interaction you have with someone can impact their life. A "Hello" can lead to a million things. A simple conversation with a person can stop them from walking to that bridge they were going to jump off of and ypu may not even know it.
You do actually have a purpose in this life. The only way to find it is to get into that darkness and get real with yourself. Find the issues in your life, find what is holding you back and make the change. As you clear the clutter out from around you, you'll find that light. Just be patient.
