Think hard. The reference in the previous post is to someone who has been advertising on this site, & whose post has just been deleted for that reason. It could well be (although I have no personal knowledge) that interest rates from that person - or from anyone else willing to lend to someone with a poor credit rating - would be pretty high.
You already have debt problems. It is rarely advisable to try to deal with these by getting more credit. Far better to try and confront your problems by getting advice on how to get out of debt. You could go to local CAB, or contact CCCS or Payplan. If you have low income and no assets, maybe bankruptcy could be a solution.
