Dear Saad
One thing that you had better do with yourself is not to hate any knowledge. Sindhi is one of the historical subjects of the region. People who speak Sindhi love their language just like you love the language you speak at home. In order to bring this subject in your good book try to allocate particular time to study Sindhi at home discuss your problems of Sindhi subject with your elders at home learn some commonly used Sindhi language vocabulary.
