Attempting to Navigate the grief storm.

I am new here today. I had been searching for a safe zone to share deep pain and grief. I lost my beautiful mama one month ago . I was also her caregiver for over 15 years.
She was not only my best friend, but my life. I was her live in caregiver, so you can imagine the overwhelming sadness and empty feeling I experience every day.
I have essentially had to plan her burial and simultaneously trying not to focus on feeling the true depth of my pain, empty , sadness, lonely, scared, angry, broken, grief.
I have been attempting to decide between cremation and traditional casket burial. I finally decided to go with traditional burial. I just could not get past buring her petite little body after after she already endured with the 10 day long hospital stay and the 10 days in hospice at home before she passed away.
It was extreme painful and difficult over Thanksgiving. It was the first one without my mama, and it was also the same day of the week she left me.
It seems like I'm never going to fill that empty black hole left inside of my heart.
