Today is the Birthday of my late Wife Anjli.....fuck....
I lost Anjli in Jan 2017. We had gone though a terrible 2 years previously with her mother, who had an aggressive form of cancer. Anjli was incredibly close with her mother. She battled depression and ultimately took her own life. When you lose a spouse to depression you go through the "what could I have done differently" scenario.
I'm so sorry.
I lost my sister 5 years ago to alcoholism. The loss was very difficult because even though she was 6 years younger, we couldn't have possibly been closer until the last 3 years or so, when she went into isolation. She had a death wish and no longer saw any value to life. The grieving process varies with each individual. Guilt is self-inflicted pain, so don't go there...coulda, shoulda, woulda, and what does this accomplish other than to punish yourself? You deserve to live a fulfilling life and even though death of a loved one is tragic, life is for the living.
