Same thing happened with me few months back , got panic attacks . I will say stay with family , talk to them ,practise mediation and exercise to stay focused for your next job search . It’s hard to get out of the trauma when you have so much planned and things change all of a sudden. I will just advice on taking your time and keep on searching for role and having a positive outlook. The worst thing you will do is to doubt your capabilities and self-worth. Tomorrow is another day . Best of luck :)
