Language is leaving me in silence

Almost didn't make it on the stage. She was silent and I can see the longing in her eyes as if it was telling me, "just wanted to hear his voice". Have tried my best to uplift her mood but I don't think I can fill it in for him. Sometimes I just wish I'd take all the hurt of my kids especially now that they are being more expressive on what they want and what they need. I tried to reach out but just got rejected. I feel so mad for hurting her.
