Debt consolidation feels like it was a scam.
Sounds like it, whatever that was that you signed up for does not sound like anything people recommend doing. If anything you could try doing promotional balance transfers onto a lower interest rate credit card if it gives you say 12-24 months 0 interest rate - that strategy is only temporary to give you some more time to pay things off.
When struggling with multiple credit card balances you essentially need to decide how you want to pay them off (debt avalanche vs snowball method) e.g. pay the minimum on all the cards except one of them, that one you pay as much as you can until it is paid off, then keep repeating until you're done with all the cards.

And in the meantime obvs stop using them until it's all paid off.
But I have such a poor credit score now that I cant imagine anyone renting to me now.
Yeah that might be tough. Maybe living with roommates or temporary prepaid subletting is an option? Those sort of arrangements are less likely to run credit checks.
