Tension - All of us have it

There is always something which is running in my mind which keeps me aloof from everything... May be thats what is "Tension". In physics "Tension is a force. It is an external stress tending to pull an object apart", now is that what happens to our minds as well? Is it really a force or an external stress which pulls or separates you from your true self? I have always been thinking about tension and how people tend to change in their behaviour (not intentionally though) when they are stuck on something and it seems like the world is coming to an end, coz there are no solutions at near sight. Everyone of us have tensions and I am not left out either, I keep looking for some questions which are unanswered and I am sure I would get them at the right time during the journey of my life. I believe in God and when I dont find answers, I leave it to him, he's the one who will show me the path. May God Bless you all !!!
