My daddy had bowel cancer, I inherited it, but I had major surgery, had part of my bowel removed, had a colostomy for a year, they said I was high risk due to my daddy's condition.

I'm ok now, had colostomy removed and dodgy part of bowel removed , but in that time, I lost my daddy,  he passed, it hurts so much, they say pain gets easier, it doesn't, I miss him every day, been 3 years, his ashes still in my brothers house, can't bear to part with him, when will.pain ease? Don't ever want to forget him ever. Just don't know how it what to do with lose
