My Childhood Blanket Habit...

I've always had this weird thing for my childhood blanket. I still keep it in a drawer at home even though I haven't used it since I was like ten years old. It's not that I'm nostalgic, but there's something about holding onto it when things get stressful or overwhelming... It's comforting, I guess? But then again, I have this weird anxiety when I think people might judge me for still having a 'childhood security blanket.' So here I am, wondering if everyone has an old comfort item from childhood they secretly hang onto... Is that normal? Or should I just let go and be done with it already?
