So sorry for your loss.
Unfortunately, I lost my dad to an industrial disease when he was 66 and I was 28.
I am now 70 and lost my mother this past June. She was 107!
Although she was in a care home for the last few years, she was reasonably healthy, right to the end.
She is frequently in my thoughts and I remember many good times and great conversations together. I will never forget her laughter and her quick wit!
Even though she lived to 107, as anyone who lost a loved one will know and whatever age they live to, it is never enough time together.
I am in a 'caring' profession and I frequently attend the event of a death with first responders. After the first responders leave, I stay for a short while to offer compassion and advice to family members left behind. Just helping them with the initial shock of their loved one's death not only helps them but helps me come to terms with my own losses, also.
Time does heal but just remember that the loss of a loved one affects everyone differently. What you are feeling is quite normal and never be afraid to talk about it.
Also, grief counseling is of a great help to many people.
