Not my generation, but millenials and younger will no doubt experience a plethora of mental health issues.

My generation, and those mature enough, will turn to books, build things, hunt, fish, and learn to trade. We'll all survive in that year, or years, it takes to get back to normal.

Every study I've read indicates it will take a bare minimum to get us back to the late 90s level of technology working. If it ever does happen, start disconnecting fuses, pull the battery from your car, battery from your phone, or power down everything you can. The most disconnected and powered down things you can have the more of them that will survive.
