sometimes you just cant explain why your sad..

In life sometimes there are situations where you cannot express your griefs and sorrows to anyone.Sometimes when you think about past and all the bad happened to you,you feel sad without any reason.Sadness comes because of many reasons.Sometimes you face family problems or sometimes you may face phsical ailment oof your loved ones or may be of yourself but still life moves on.I believe everyone in this world has to bear his or her pain on his own.No one can make it lesser.and so thats why it happens you cannot even tell your pains to your loved ones and that causes undue sadness
