See, I would never say something like that to my kids because I don't see myself as crazy and it would seem perhaps unsettling or upsetting for them if I referred to myself that way. A 14-year-old is plenty old enough to explain what your meds do. For instance, when I was on AP, they helped me with racing thoughts and ruminations, so I would just explain that I have times when I get stuck thinking about things, kind of in a loop, and the AP helps break the loop so I think more clearly. That would be a pretty easy explanation for a 14-year-old to "get".
