17 and need a Job ASAP help?

I'm 17 and I am in the process of getting my GED at the collage. I couldn't finnish Senior year due to moving and my credits meaning less at the new school than they should. I need a job to help my dad pay rent, he will kick me out on my *** at 17 and I don't wanna move back in with my mom. I have 3 months to get a Job, or get out. I have filled out about 15 applications and no job has even givin me a interview. I have bad hand wrighting, & I think I just make myself look stupid. What kind of stuff is good to put on a application that will help? What can I do? Any jobs you reccomend applying for? Any type of Online work I could do from home? Any odd things I can do that will hire me on the spot? Anything helps.
