I'm in my late 20's. I have graduated from college at the top of my class, have close friends I've had since I was 12, and am in a caring and loving relationship. I also collect toys and dolls. I have a large teddy bear collection. I plan on building a dollhouse for my Barbie dolls. Heck, I am currently working on putting a wig on a doll that I've repainted!
As a few people have already said, there is nothing wrong with playing with toys and playing games. Be a responsible person. Be trustworthy, dependable, kind, inspiring - these are all things that you can be now and can continue developing as you get older...but your interests and what you find joy in don't have to change.
I hope this helps. You're doing great and you have a bright future ahead of you 😉
