Sister,
Baba never like coward devotees. They want them to strugle. They want them to see strong. If you can't face small truth of life, How the bigger one of the life. In every family there is disputes between brothers and sisters, spouses, with parents, differences of opinions. But, does some one leave his home due to this? You are part of family and will remain if you have adopted Sai as your lord even once.
Have Faith! Have Patience!
May Sai Bless you and be with you!
om sai ram!
