Minimize your expenses. Find and work any job, it does not have to be tech related. You can quit once you find a tech one you care about.
Put all gains towards a safety fund (enough to support your expenses for 3 months) first, and after that fully towards paying debt back, until you have paid it in full.
A pain, but that's life. Sometimes, you just have to grind. In the future, you'll be glad you got rid of debt and your struggles are behind you.
