Lost my job yesterday - freaking out

Laid off due to "restructuring" at a company I was at for 7 years. First thing I did was panic about how to tell my wife and whether we can make mortgage. Second thing was spiral about being a failure. I know logically that getting laid off happens and isn't about my worth but my brain is NOT having it. Anyone been through this? How long did it take to stop feeling like your identity got erased?
