I too think it's quite normal :/ It's common for game players I guess.. Some of my friends were like that too. They wasted money, time and sleep due to some sort of games they're playing. A better term would be "addiction". And in my opinion you're never too late for anything. Be it plushies or dolls or childish games, or even drugs. I was addicted to Facebook and Twitter once, until one day a day before an exam, I messaged all my friends goodbye and told my mom to keep my phones and computers for one whole month. It worked. Addiction over.

Don't feed on stuff you feel addicted. Throw them away, I mean literally. I threw away my DVD collection, felt guilty and regretted spending money on them, I taught myself that it was a lesson and that they were junks.

Good luck with overcoming your addictions
