be wary of credit counseling agencies; many of them are ripoffs, and using one - so i’m told - has the same impact on your credit report as declaring bankruptcy
get the numbers together, and make arrangements with each creditor individually if possible
most reputable firms are happy to help you work out a plan you can stick to, but note: if you say the magic words “bankruptcy lawyer”, they will not talk to you at all
