Is it normal to want to wear dipaer and wet your pants at age 18???

i am 18 years old and ever since i was 7 i have had this urge to want to wear diapers. i asked my mom one day if she would buy me some dipaer and to my belife she went out and bought them for me. i love they way they feel between my legs it makes me feel safe. i have one friend that knows that i still wear diapers and he found out one day when he was over at my house, he saw them sticking out of my shorts and asked why i still wore diapers, and i told him straight up i like the way they feel. i have tried to tell my youth leader at church where i help out at it's called DC4K(LOOK IT UP) i went up to her and was about to tell her about my seceret when i started to pee myself thank god i was wearing a good thick diaper cause i would have looked like a baby in front of her. So the point i am trying to make here is, is it normal to want to wear diapers becuase i am having troulbe. does it mean i'm weird. i don't know some one help please thank:)
