Dear Durga, 

sorry that you’ve been brought low by the death of your mother, it is such a painful loss to bear.  There is a group here called I Miss My Mom that might be helpful to you.  My mother died nine months ago and this site has given me some strength and context — sometimes just knowing that other people have very similar feelings and behaviours in bereavement has made me feel less crazy in the dark days, hope you will find the comfort and support you need.
