Tired in fight between wife and mother

There is constant drama in home. My wife and mother has not spoken properly for past 3 years now. Daily I struggle to maintain balance between two and get sandwiched. More I try to maintain harmony more fight happens. They both are educated and well learned but they just don't like each other. It has taken a toll on my mental health and my work productivity is also suffering. I am getting fat (stress eating) and random health issues are coming. Please suggest how to deal with this? 🙏
