Get somebody (hopefully a good friend, relative or partner) to listen to you unpack what you're feeling and to coach you through finding your feet again. Sorry to hear this. A company i worked for went to the wall the other year and it was a shock to the system.
Happened to me twice; what I wished I’d done:
CHILL you’ll find another job
ENJOY work free days
Have FUN networking
Both times I did move onwards and upwards, you will too! Do the work to manage finances & getting next gig but find fun.
Remember It was a numbers decision; you are AWESOME!
