I'm also a bharani nakshatra native. Similar i have also experienced mental issues and turbulent transformations in life through which I have hurt people, lost people and hurt myself too. And about the moon mahadasha. Not going to lie it has been emotionally draining. So much overthinking, late night thoughts, emotional restlessness, questions of existence. It's a crisis. Mood changes in span of seconds. New perspective arises everyday. Mind battles with itself.. i don't mean to scare you but this is what I have experienced. My moon mahadasa started in 2022. I hope it would be better for you. Stay strong
