Starting To Wonder What Will Become Of My Life

Yes.. I know. Post 14 of 2 days. Jesus.

I KNOW I'm going to be a tattoo artist.
But I haven't gone to the tattoo shop in over a month. Due to my personal life making me too stressed out to deal with anything else.
I also am losing faith in my artistic abilities. Yes, I know I am good. But I can't draw anything off the top of my head, except cartoon stuff like skulls and graffiti and stuff. That show more of my outward personality.
When it comes to REALLY drawing, I HAVE to look at something. I can't just come up with my own design. I have to look at a drawing, and go from there.
But I CAN draw. I'm not like Maria. I don't pretend I'm bad when I know I'm not.
I know some of my stuff needs work, and that's when I say I'm bad. When I actually TRULY believe I am. But I'm honest with myself. I do have artistic talent.
Just not enough...
So I'm starting to doubt whether or not I'm good enough to become a tattoo artist.
Yay for self consciousness. -.-

And if tattooing doesn't work for me... What else is there?
I want to be a cook, but I have no patience and don't want to take the time and effort to pursue that.
I want to be a singer... Apparently American Idol is coming to Central Oregon this year. Or somewhere close by. And I thought about auditioning. But again, I am NOT that good at singing.
I CAN sing. But I'm not breathtaking... I can definitely use some work on that. THAT's something I know I could do. I WOULD take time and effort to pursue that. But I can't write songs. So where am I?
Nowhere.
I don't want to have an ordinary job... Like working at a store or something.
I want to do something I love. But it seems I don't have the potential.
