I feel like a loser hopeless a faliure at life?

I'm sorry you are having this discouragement with your life. I will tell you that in general teen years do suck. I'm pretty sure even those who look like they are have a great time might be faking it. But sometimes faking it does work, because it becomes habit. But back to the real world, do you want to go back to public school. Do you think that would help? Snowboarding, golf, video games ... you only have yourself to please. Are they fun? Why do you have be great at them? Same with art; just creating something is pleasurable. It doesn't have to be museum quality. Heck, you don't even have to save it. Girls? don't worry about that. That just happens when you don't expect it. Believe me you are an adult a lot longer than you are a teen. Be patient. Best of luck.
