I think all of this is normal.
I left my H when my children were in college. What I do remember from when they were growing up, was not normal.
My son at age 12 took a nap, he woke up crying. Took me 20 minutes to calm him down. Would talk to him about his feelings, told me that he saw himself at the window, and that he wanted to jump. He got a full scholarship to a great college, based on his SAT scores, not his school performance. Lost it within 2 years.
My daughter, a lot like me, just got out of an abusive relationship.
Did they regress while growing up? Yes they did, they were bedwetters till age 5 or 6.
You did the right thing, the children will soon start to blossom. Wish I could have been brave enough to do this when they were younger.
They will thank you for this
