Well... Why don't you try to get a job that doesn't require ssn? Or better yet, apply to city college in your state in the Spring semester. And don't commit suicide because all problems are temporary. Just wait for the vote on the Dream Act.

I went through a similar situation, where I tried to go to a private Christian college (Bob Jones University). But clearly, God didn't want me there because all the doors to that path were closed. Maybe God's will for you is not to attend Brigham Young...
