NYT has a piece on the subject that became an important part of my life recently: dealing with toxic parents.
My own mother can be pretty bad at times, but she is really nothing compared to Anil's mother, who is by far the most abusive person that I have ever met in my life. Anil is a wonderful person and deserves all the happiness in the world, so it breaks my heart to see him sacrifice his life for his crazy (literally) mother. It also saddens me that I do not know how to help him. Sometimes life can be frustrating and unfair.
