Being a Mom Hurts

We're just hanging tight until Landon's pediatric urologist appointment in two weeks. He is still wetting 4-5 nights each week, and now it's starting to seep into the daytime. He has had two daytime accidents in the past two weeks. He hasn't had a daytime accident since he was 2. The worst was his last accident...at school...on the playground. He said that he didn't even know he had to go and that it just came out. It embarrassed him badly. If people are in the house (other than me, Christopher, and Carter), he hides to put on his "nighttime underwear" and changes out of them first thing in the morning before he even leaves his room. I continuously tell him that he doesn't need to feel ashamed or embarrassed, and that the doctor is going to help us. He talks about his upcoming appointment (specifically the blood drawing part) almost daily. He's full of dread and angst and embarrassment. And it breaks my heart into a million little pieces. I don't know how to fix this. No one told me how bad this motherhood gig would hurt.
