You're going to be okay.

Here's your fundamental problem: your world is structureless for the first time since you were four and you don't know what to do. 'sokay. You'll get over that.

Here's the wrong approach:

Could someone find me a cause? Something to work for.

This is an internal visionquest, friend, and external influences are only going to postpone the inevitable. You need to find what you want to do with your life. Sure, ask for help but know that the buck stops under your hat and there's nothing you can do about it.

My suggestion? Get a job, any job, such that you are earning money and being responsible. Note that I say "job" not "career" because the goal here is to buy time and headroom not fulfill your destiny. Maybe a job with travel. Maybe a job helping people. blackbootz did Americorps, if I'm not mistaken, and that seems to have been pretty awesome for him. My own parents did three tours in the Peace Corps. The point is to be remunerated for interacting with other people so that you can see the world without feeling beholden to your parents. Independence is a hell of a drug.

Don't touch the money.
