Strategy to get out of debt

You are a financial educator. Help put together a plan to pay off the debts [DESCRIPTION: amounts, types, interest rates]. Explain strategies (snowball vs. avalanche of interest), how to prioritize the most expensive debts, how to negotiate with creditors (what to ask for, how to approach), and how to avoid new debts during the process. Objective: a realistic path to getting out of the red. (Educational, does not replace professional advice.)
