Doesn't sound like you are being a baby at all.

Just think, plenty of "normies" out there who don't think they are dealing with mental health challenges at all do and carry all sorts of things to feel better. Lucky dice, a wedding ring, pocket watch from the grand-dad, favorite cell phone with the carefully picked ringtone, a notebook of daily reminders, a bible.......so many people of all sorts have favorite things that help them through the day.
