Private Loans when you have bad credit and no signer

<p>I am 21 with bad credit due to loss of job from two years ago and medical bills. I recently quit my job and now only receive social security once a month. My mom won't co-sign because she doesn't have a job and I don'[t have anyone else. I need to get a loan for about 15000 by the end of the week or else I will have to leave the college. Can someone please help? I have applied to dozen of places but it is always declined because of collections from job loss and medical bills.</p>
