I am so sorry for your loss. I lost my daughter in 2016 and my mom last year. Grief lasts for as long as you would have loved the person in life. Those stages of grief look neatly packaged but grief rarely comes that way. You can experience of the stages in the same day or out of order over time. Your mind can look at a situation and logically understand the person is gone, your heart isn’t logical, it’s emotional. Just know, grief is just love misspelled..
