In short, no. There have been two times when my ABDL desires “disappeared”, although I now know they never really went away.
The first time was when I was a senior in high school going into my freshman year in college. I was very busy with classes and getting used to life in college, so I didn’t have time for diapers and my desires were placed on the back burner. While I was happy, at some points I felt a certain emptiness that I was unable to explain. By the end of freshman year going into sophomore year, I was settled in and my desires came back, rather quickly in fact. I even mustered up the courage to buy my first pack of Goodnites when I went home for the summer, my parents went on vacation for a few days and my brothers were at camp. When I went back for my sophomore year, I decided step up and buy some actual adult diapers. The desires were there for over a year.
The second time they went away is when I actually tried making them go away. This was partly driven by the mirror thing and partly by a really bad leak incident. At first it was somewhat tough, but after some time I felt like I had sufficiently kicked my desires (although, unlike a certain member, I didn’t come on here gloating about how I successfully got rid of my desires and encouraging everyone else to do the same). But, I had the same feeling of emptiness return, the same one I mentioned earlier. This time it was a lot stronger. I truly felt like a part of me was missing. Eventually, this began leading to feelings of depression. After a while, I realized it wasn’t right to ignore something that it part of who I am. I decided to embrace my little side. I got a pair of footie pajamas, I started wearing diapers more regularly, and I began getting more ABDL stuff such as pacifiers. I felt like I was happier, complete, and it makes dealing with stress a lot easier.
What all this taught me is it was better to embrace myself and everything about me than try to ignore one facet or another. The path to self-acceptance becomes much easier this way. I love every aspect of being ABDL, and I wouldn’t give it up for anything. As for the mirror thing, I found that by using my imagination instead of seeing my adult self I can see a younger version of myself, someone who never really left childhood. This has also made self-acceptance a lot easier, as it makes looking at myself a lot less scary.
