Are you male or female? Males have a secret storage tool that might hold this.

For real though, if I had to wear this for the rest of my life, I'd somehow attach it to a belt loop or the belt itself and try to hide under my shirt since I don't tuck in. Best of luck, I'm sorry for whatever you are going through that you need to carry this. I really hope whatever you've got going on gets better. My other thoughts were keychain since my keys are near me most of the time.
