Been going through a bad chapter in life, life is

Been going through a bad chapter in life, life is nice and calm but with that safety comes all the memories and grief I buried in chaos. I lost my son September 4, 2019 two days after his 20th birthday. I'm isolating myself and I feel like I can’t come out of this stage if depression, I'm living normally but its so flat and numb and I don't want to be a part of life right now, I know theres no Choice I have to keep breathing but fok im done.
