Whatever happens, you've done the right thing. You should also find that you have more knowledge and skills in the locker than you realise. That'll come in handy if you have to jump sectors (plus you have good people/customer-facing skills, right? Those are priceless. Pretty much every role I see has something about needing 'Excellent communication skills' and suchlike). And if you find no one will give you a job, you can always work for yourself. It's tough, especially right out of the gate, but there are certain compensations (and if your boss turns out to be an a-hole...well, who do you have to blame but yourself?
).
Nothing but the very best wishes here.
