Familiar story to me too. All I have left is a decently large old tax bill which (thanks to my fiancé) can be tackled soon. I had to get on payment plans for medical bills, some as small as $10/mo so I knew I could afford it. Fortunately by being honest with each debtor about why I had gotten so messed up meant they made the debt interest free and at reasonable payment amounts.
I also had some legal fees along the way that my parents paid.
Getting past my shame and lack of motivation took a minute but by about 100 days I had sat down and listed everything I had to address, and the feeling of accomplishment I felt was awesome.
My credit is not good still but I have been able to get my own credit card.
Life wreckage when drinking can have so many faces and be wide reaching- for the non reasons you mention (I went a long time just not opening mail!) and it takes time for some of us to get back to par and move up.
Regretting the past doesn't help and dealing with the reality is the only way I know to get through The rebuilding.
