My mom found my diapers

So a bit of a backstory before i get into everything. I, 16M, have been secretly wearing diapers for a few months just as way of comforting myself. I don’t know why it’s happening, or why it makes me feel the way it does, but i’ve just been going with it. A few months ago, my mom was cleaning, putting away laundry, or something, and she found a bag that i had hidden behind something in my closet. She didn’t mention it to me, assuming she was too scared or didn’t quite know how to approach me, so i didn’t stop. A few weeks later, she found another bag i had (i had thrown the previous one away, this is a new one). She then called me to talk to me, and we had our conversation. She told me she was scared and concerned for me, and didn’t quite know how to approach this. But to sum it up, or at least what i gathered from it, she felt very uncomfortable and basically told me i couldn’t do that. Of course, her being my mother and me caring about her, i obliged. But, the need came back and i bought a small sample pack. And of course, i didn’t hide them well enough, and she found them again. We had another discussion and i really couldn’t think of what to say to her. She seemed genuinely concerned, not like she was disgusted and shaming me, just that motherly concern that all mothers have. I tried to tell her what i could manage to say, but nothing seemed to reassure her i wasn’t in danger or being sexual. I haven’t used any for months now, and i really don’t know what to do.

Does anyone have any suggestions?
