Think goal.

After getting help for her son only to find he is getting worse a Mum ..... but .......

That sort of thing.

But if getting help is half the story? Look for the one thread that ties the two halves and use that.

What sets the story in motion.

Everything is normal then...

Does he kill the family dog? Harm a neighbor kid? Does he harm the psychiatrist who is helping him?
You say he is violent but instead, you should give us a specific example of violence, the act that sets the mother into action.

Thank you for the feedback. Will work on a revision.
