Is there a 'test' to find out if one is a lightworker, wanderer, indigo, crystal child, etc.?

I just know I'm not from this planet - I feel like this civilization is a far cry from the peaceful world I'm used to. I often feel lost and powerless, and homesick when I look at the stars at night. I'm aching to know why I am here and what I'm supposed to do - I have strange coincidences happening to me (like seeing 11:11, etc.) and I know it's a wake up call but for what? I'm waiting, anxious to remember something I used to know, does anyone else have this feeling, and can you lead me to books/websites dealing with this?
