Sorry for your loss, it is very hard losing a parent. I lost both of my parents within a year of each other, both of my parents were 50 years old when they died. My dad died from cancer and my mom from a massive brain aneurysm that killed her instantly at home. Unfortunately I walked into the house and found my mom after her death. I was 24 at the time when I lost the both of them.
It was a very hard and traumatic time in my life, still think of them both every day. But the way I got through it was thinking of other people who lost their parents at a younger age or maybe in a more violent or less-peaceful way. I also lost my entire family in various ways of death years after my parents, my sister is the only living family member I have left.
Life is short, and it does suck at times. You have to make the best of it. That is my philosophy that I live by. I go to work every day and live my life, sad at times but you need to push through. Best of luck dealing with the process, it does get easier, but it is never forgotten.
