I am an adult now, but as a child and teen I was an avid bed and diaper wetter, so I understand your position. Since you have checked for medical reasons, I suggest you look into the emotional side. It is quite possible that something that happened back when you were 14 caused such and emotional upset as to restart your wetting pattern. Maybe a stressful situation is still continuing at home or school. The continuing wetting can cause the emotional problem, and the whole thing can snowball on you, keeping it going. It would be wise to spend time with a counselor or psychologist to discover if this could be your problem. It does not mean you are crazy. Just that you have something unresolved that is coming out in this way. You have nothing to lose and your dryness to gain. Hang in there.
