Mum passing last year after Mother’s Day.

Wanted to know if anyone has gone through losing their Mum through years of illness and being there with them on their last breath?
She passed the day after Mother’s Day in the hospital.
I struggle with my grief and wanting to know if she is around me as I don’t hear her or see her.
I struggle with the images of her passing.
Dealing with feeling alone, sad, my body is stressed.
Would love to know what helps others move through it all?
