How do i tell them? Do i need to?

How do i tell them that I still get nightmares?
How do i tell them that i cant go back to sleep whenever i get the same nightmare without sounding like a kid asking for comfort ?
They said tell what bothers you to the people you trust
But how am i going to tell them that i still wake up midnight with heavy breaths and tears
How do i tell them that the voices still echoes and it hunts me till every last second of breath
How do i tell them the heavy feeling, the scratches i did so i can calm myself
How am i going to tell them how many times i have hit my head hoping they go away
How am i going to tell them that i sometimes stay awake the whole night so i can skip the same dream
How do i tell them and explain why i need to whisper to myself and reassure that im safe
How do i tell it to the people i trust that they are the reason why im awake at night
