It's always pretty awful when your alone and unsure, time to think is good and bad. I was made redundant in 2006, had a mortgage and managed to get another job in time to manage the finances. I got hit with a pretty severe MS attack in early 2016, couldn't walk, talk, type for 2m, thought it was all over, a £500k mortgage, in the process of increase to £650k and halfway through a house renovation. Bugger me life looks different now, I recovered, kept my job, sold the huge noose and downsized.
I realised there's always someone better off and worst off, keep your confidence and sell a few things you don't love or need if you have to.
