After I lost my wife I lost interest in everything. Depression is real, and it's paralyzing. Once I broke free it was time to see if I still had interest in pinball and if not sell off the load of em. I had my FH partially restored and while that was going on I bought TH. My love for pinball was reignited. I also bought a TAF project pin.
My only advice:
1.) ONLY work on your machines when the kid/s aren't around or sleeping. Devote the rest of your time to him/them.
2.) The world has turned into an angry intolerant pile of dog shit. Your hobby keeps you away from having to deal with the nonsense
3.) Don't obsess over a pinball machine that's down. Keep your focus on the things that "truly" matter in life.
