I really need some help. (This is serious to me)

So in the past year or so I’ve had bathroom problems at night and I wasn’t able to wake up and I wound up wetting the bed. it happened a few time, but I’ve just pushed them to the side thinking it’s not that big of a deal and sometimes accidents happen. It’s been a few months since my last accident but 2 nights ago it happened again. I’ve never had a problem like this before and I’ve never not been able to get up in the middle of the night to use the bathroom. I’ve done some googling and I’ve read that it’s common with kids who have ADHD, and I was diagnosed with it in first grade (I’m 17 now). I’ve also read that sometimes it happens if your constipated. Now to be honest I don’t usually eat like a normal person should everyday because the medicine I take for my ADHD take away my appetite, so maybe it messes with my digestive system. But overall I have no idea what to do. I’ve talked to my mom about it and she’s not judgemental at all and I appreciate it. The only problem is that I don’t want to bring this up to her again and her take me to the doctor. That will just make the situation more embarrassing and awkward, especially since my doctor is a man.

So just if anyone has any good advice on what I should do or if anyone has anything to add, please let me know.
