I mean, you're not alone, the entire software industry is like this right now. Fresh grads, senior devs, etc. It's brutal tbh and the rest of the job market isn't much better. The only people I know to have constant employment are blue collar workers, laying tiles, flooring, roofing, etc.
I have 8 YOE, which in "normal times" should land me a job in a week. I've been looking for over a year now, written easily about 100 applications over the past year, did 20+ interviews and got about 50 rejections and the rest ghosted me (rough numbers).
My plan is to continue being on benefits (I try only taking the absolute minimum) until I can start my own company next year. That's the only way I see out from this absolute joke of a job market and not be in that situation again (remember 2008). And renting out my house, doing AirBnB, etc. - anything just not to land stocking shelves at Walmart.
So that's my plan, really. Try to look for dysfunctional companies and then copy their business model and make it better. Also, keep your portfolio active, don't let your skills degrade, etc. That's all "advice" I can give you. You're in my prayers, of course.
