Hey man, I feel you. I've been a diaper lover all my life and its always been in hiding, which I very much wish it wasn't. I've tried to stop wearing them more times than I can remember, but always I come back to it. My parents know but since I've tried to go to thearopy for it, I assume they think I'm over it. But what has helped to weaken the desire is whenever the very thought comes into my mind I replace it with another that interests me like.... how the jedi fight scenes in the new stars wars could be improved. then I linger on it for a while. If I think about it again I do the same thing. This methode has actually kept me away for months. And even if you give in again, trying not to think about it will keep the desire to wear them weak so you don't feel so overwhelmed that you feel like if you don't get diapers you'll die. I hope the best for you, but seriously, its all in the mind, for me its always started with my thoughts, so replace them. I have a weak mind so its never really cured me, since just yesterday I was wearing one, even with my older bro present, but I've learned that cargo pants and shorts make it less obvious, and it blends the sound in as well, and honestly, those who don't know, its really the last thing they'd expect to see a 22 year old like myself wearing diapers. But your parents sound like mine, inquizitive. I do have to be careful around them. but anyway, sorry, I'm not helping too much, but try the mind thing, turn away from images you see of them. I wish I could hear how it goes, but I'm on here very little since my parents have it password locked, I was lucky to get on tonight, but my mom left me alone with it on.
Well better go, my bro may be home soon. good luck
