My son has been acting out because he doesn’t know how to express his emotions and I feel like I’m completely failing him because I can’t teach him to express then because even tho I am an adult no one ever taught me how to express my emotions either & I know he’s suffering & I just really don’t know how to help him it’s really heart breaking, I’ve been crying all week 😩
