'who am I'

'Who am I?' this is a question we keep asking ourselves at times.Am i a mother, a daughter, a wife, a daughter-in-law and the list is endless. Do we need to identify with one of these roles at some point or the other in our lives. The other day one of my friends was very restless as she had left her children with her husband and she could not enjoy where she was as her mind was at home and she was kind off feeling guilty + a feeling that they would find it difficult without her. And i could not help but tell her that she existed independent of the people around her. She replied saying she knew but she could not help feeling that way. Is this because our self worth depends on others, a validation from people around us, a feeling that we are needed? Is it difficult to be just be..
