Teenage bedwetting : Parenting

Hi! Here's my second account just to make sure my son doesn't get recognized :) Also English is my second language so please be comprehensive.

So I'm a single mother to a 17 years old son and a 15 years old son. They're dad was abusive and he left when they were 8 and 6 years old. My youngest didn't get to affected by that but it hurt my oldest so deeply. When this happened he started wetting his bed again. He did a lot of therapy but it hasn't helped resolve this issue to this day. He's really popular in school but never had any sleepover due to that. He also has a crush on the same girl for so long but rejected her because of that and he was so heartbroken. Lastly, he plays football and had the opportunity to attend some kind of football camp to play in a league when he goes to college but refused to go because he had to sleep there.

As much as I understand he doesn't want to be caught wearing his night "diapers" it keeps him from doing so many things in his life. I don't want to complain but I have to go buy the diapers really far away because he doesn't want any of his friends to see me buying them. Has anyone ever had that issue and resolved it? No doctors or therapist were able to help me with that one. He is a beautiful young man and I wish he could live his life to the fullest.

Talk about what it means to be a good person. Start early: When you read bedtime stories, for example, ask your toddler whether characters are being mean or nice and explore why.

Edit: The issue isn't physical, he has passed all the tests and there's nothing wrong with his body, the issue is most likely psychological which somehow breaks my heart even more
