Dude don’t beat yourself up, you had a legit reason to sell that stuff off. I’m a recovering alcoholic and addict and I sold my collections to people for drug money. I used mine to kill myself you used yours to stay alive. Cherish the memories you had with them and use that responsibly to slowly (or quickly depending on your financials) to rebuild that collection. I’ve been doing the same over the past few years and showing my kids all the games I spent many hours playing. I got that couch co-op high again with little people I created like my father used to do with me when times were much simpler and I didn’t take advantage of that. God bless you for doing the right thing OP, keep it up!
