Let me offer an opposing and much more optimistic perspective Lostsoul2.
I'll start by asking whether it seems more rational to listen to people struggling through life with no sense of purpose, or to those who manage life well with a sense of purpose? One path suggests that we're all evolutionary accidents with our lives dictated by luck, while the other path suggests that there is a creator who made us with free will to make decisions that affect our lives. Sure, there appears to be chance events occuring around us each day, but to conclude that there is no right or wrong decisions to make or no right or wrong direction in life to pursue is a depressing position that fortunately is entirely wrong.
The questions and concerns you ponder about life while looking in the mirror are appropriate and common. As we grow older, some people mature enough and think deeply enough to care about such things, while too many others just seek daily happiness with shallow worldly activities. I compliment you for seeking a deeper truth about yourself and your life. I could share much about this, but let me start with one video that I think applies to your situation. It's a Christian sermon, but a short half hour one that you should find interesting, entertaining, and maybe... inspirational.
