Yeah that's tough, sorry to hear it... It's been a while since I've been in that situation so perhaps perspective is limited, but best thing is to just keep moving forward as best you can.

My advice -- try to keep emotion out of things as much as possible and look at the cold, hard facts. Where can you cut expenses? Is (the irrational emotion of) pride keeping you from (say) moving back in with family or moving in with friends? (Housing is biggest cost for most people)

On the income side -- any way to upskill? Trade school, apprenticeship, etc?
