Ask HN: Advice for newly laid-off dev over 50

So, I was laid off last Friday after management discontinued a software product I had worked on since inception (8 years ago). While I was getting a feeling that this was going to happen - the axe fell sooner than expected so I’m unprepared. I spent the weekend dealing with the surprise and plotting a course forward. From what I’ve been reading, apparently I’m screwed because I’m in my 50s, the job market is weak, and my network is almost non-existent (focus has been on family). Among things In my favor is that I have a very strong technical background (full-stack developer - primarily Microsoft). I’ve made sure to keep myself current and incorporate new technology in recent releases of the (now retired) product. I was also getting up to speed with react/Next.js in anticipation for a proposed project (before funding ran out). My employment history is solid with several well-known companies in the mix. I also live in the New York metro area. Among things that are going against me (in addition to what I wrote above) is lack of any recent job hunting experience and also technical interviewing skills. I’m curious as to what advice HN could offer to someone in a position like mine?
