I am so sorry for your loss. Experiencing intense sadness and anxiety after this monumental loss is completely understandable. Grieving can take time and it is important to be patient with yourself. Allow yourself to grieve and also focus on self care - what do you need right now? Social time, meditation, time in nature, pleasurable activities, talking about your pain, journaling, celebrating your mother's life, exercise, health eating, etc are all suggestions that may help. Do some research on self care and grieving in order to arm yourself with tools that may help you get through this. In person grief support groups or therapy may also be another resource for you. What are your thoughts on all this?
