I think you are still thinking about the diapers way too much. Is it a good brand that you’ve tried before and trust? Stop being so nervous about being around people. I recently have started to wear around my friends as I am going as close to 24/7 that I can. I am able to hide it with smart thinking. No one can hear the crinkle unless it is absolutely quiet. The bulge isnt obvious unless you are wearing tight pants. Wear a longer, or even tucked shirt so it can’t poke out. Wear high rise underwear to cover your diaper so you feel safer.
I don’t know what else to tell you that no ine else hasn’t repeated multiple times. At least you are trying and building the courage. And remember that if anyone does find out, “It’s my own private issues I’m having to deal with.”
(Screw what anyone else thinks!)
