Salution listless and disinterested

Hello Sir, My husband is feeling very listless and disinterested in everything esp going to work, doing work around the house, interacting with family etc .. it seems like he is lost and given up on hope, life, happiness... My children also keep asking me as to what is up with their father. He does not open up about what is bothering him. This is giving me too much stress and sleepless nights. Please tell me what serum I can charge his water bottle with using VK and also any switchword that I can chant on his behalf. please help Sir, please.
