This is not off track! You are right on. Insecurity isn't just a side issue, its the core issue. Listen, do you enjoy yourself? Do you have fun? Do you feel productive? Do you keep yourself healthy (eat well, exercise, sleep, etc.)? Do you have friends, either physically or remotely (hey, society on a less-traveling-is-good orgy right now, so who is to say that online communities are any less real, meaningful, or important!) And most importantly, are you happy?
If you can answer "yes" (or at least, "I'm honestly working on it") to all those questions, then who cares what you are doing? You are not hurting people, stealing, or whatever. You can be a complete friekophile gamer and still, say, invent something that makes the world a better place.
Enjoy your games!
