I need a personal loan of $6500 but have bad credit?

i have bad credit (below500) because of an ex fiance that robbed me blind & caused me to lose my 2 homes (long story) i now need $6500 to pay for a medical procedure
Update: i just checked my score & its 518 (2 pts. below what prosper.com allows) ...any other help? I can afford up to $300/mth for repayment- it just my stupid credit score!!!
