We all grieve a personal loss the rest of our life. It's not always a daily, weekly, or monthly time of grief. If you've lost your Mom, memories pop up on Mother's Day. They can be bittersweet. The same with your Dad and all other losses. Yes, grief isn't as hard after years of loss, but all of a sudden it seems like it happened yesterday and the tears come with sweet memories. Tears are healing. Allow yourself to grieve because if you don't it comes out in physical forms. I know this from personal experience after losing my daughter. I tried to keep myself extra busy and not think about the loss. I started to hyperventilate and became anxious. I was told by my Doctor that I had unresolved grief and I needed to see a counselor. After a year of talking... and the counselor just let me pour my heart out, I stopped hyperventilating and became less anxious. It's always helpful too to let go and let God!
