Re: My experience
I graduated probably before you were born (unless you were a mature student or took a prolonged course).
That kind of thing happened to us, too. Not quite the "gig economy" as we know it today, but a series of short term jobs, geographical uprootings, grotty HMO rentals, and the like, taking me to around ten years older than I infer you are today. Then came the real poverty.
Beer. 'Cos you'll need it.
