So sorry to hear about your loss. I lost my mom to ALS in 1997. She was only 61 and died suddenly. Never got to say goodbye. My dad passed away this year at 80. He survived throat cancer and was taken by a stroke. I actually had an amazing talk with him about a week before his stroke happened and we talked about everything. I'm so glad I had that moment. While he was in the hospital I visited him every day and he knew how much he meant to me. My mom visits me all the time in dreams and I see things that remind me of her. I believe it's because we never got that same talk. My dad has not visited me and I believe we never left anything unsaid.
Losing my mom was devastating but losing my dad this year really took a toll on me. I was not able to sleep, I felt depressed and just really had a tough time dealing with it. I'm still having a tough time. It really makes you re-evaluate what is important in your life. I hope you have support form your family and time is the only thing that can heal you. Forums like this a great as well. You realize how many others are experiencing similar situations. Keep your memories alive and stay strong. It will get better. Peace.
