Yeh, venting on the internet helps. And it’s always great when you actually connect with someone.

I always wish I’d learned a trade. Electrician, plumber or tiler. Get an apprenticeship, learn a trade, be a sole trader, do something physical that’s always in demand.
Plenty out there to do, and it’s ok to mourn your last job (being a student/doctorate is a job).
Connect with old friends and family. Meet some new people. Somebody will be looking for someone smart and compassionate
