I relate to this. Golden handcuffs seem great until you're trapped in an expensive mortgage in a HCOL city in a career that you despise.

If you want out, I'd strongly encourage you to start investing in that education now. Working a day job and taking night classes is challenging but it'll start building a foundation to exit -- or at least provide some novelty. I took my severance and put it into an accelerated EMT program which is giving me some badly needed routes forward.

Regardless, I wish you the best of luck no matter where you go. Sometimes we just need to pay the bills for a few years and figure out next steps.
