Fake bedwetter
When I was 14 I told my mom I still wet the bed but it was a cover... she was a public health nurse and collected all kinds of health, wellness, and sanitary products. There were a lot of adult diapers. I had a blossoming fetish and so I would help myself as I pleased to any pack of diapers or pull ups that were open. It was a dream to have this kind of access and I indulged in excess at times. It finally came to a head when she saw a diaper peaking over my waistband when I was sleeping and she came into my room. I guess the covers didn't stay in place and I was busted. When she confronted me about it I panicked and told her I'd been wetting the bed on occasion. It wasn't a complete lie. I did wet consistently until I was around 10 or 11 but had only had the occasional incident like a few times a year and all on consecutive nights. We proceeded to have a very awkward conversation. I told her I was scared it was going to happen all the time and didn't want the embarrassment. I backed way off on wearing after that. I still indulged occasionally but I didn't want the embarrassment. It was fun and exciting. A couple times over summer break I'd see how long I could stay in diapers. I only made like 3 days but it was fun.
You should have talked to her and agreed to have her start putting you back in them. Treating you like a child before bed each night.
