This is called an existential crisis. You are human and have a bigger brain than most animals. Your brain is a rut digger.
Your brain tries to get you on a predictable path. Your brain gathers all sorts of clues, information, but tries to distort them to make you keep going in one continuous direction. Unfortunately, your early information is what other people tell you and it is wrong (for YOU) at least half the time.
Eric Berne (transactional analysis) described masturbation as the first existential crisis. It's something that is immensely rewarding and you are left with the decision of whether you should do it and when and how often you should do it.
To me the best way to deal with the existential crisis is to embrace it. Don't let religion, politics, organization, corportations define your purpose.
You are free to ask yourself "What do I want right NOW?" "What can I do to bring THAT want into reality?" Or you can ask yourself "What do I want to avoid right NOW?" " What can I do to avoid THAT" If you learn to make a habit of asking those questions it's as effective as prayer.
If you don't know what you really want you need to take a long Forest Gump walk until you do. Just don't sit down and wait. That stagnation will give other people the power to get you to do what they want.
There is only one ethical or moral thing to take into consideration. Make sure that what you want doesn't physically harm someone else.
You can even join a religion, political movement or whatever if it is something you really WANT to do and you don't surrender your own personal goal.
Only be concerned about truth and reality if you really want truth and reality.
Only be concerened about what others think about you if fame and reputation is something you have chosen.
Only be concerned about power if you want power.
Only be concerned about relaxation, sexual pleasure, or whatever if you choose it.
Living a life of your choosing is as good as it gets for you personally and society at large.
