Loss changes you. I had never experienced that feeling of being so changed until my father was killed, then a year later my brother died. Losing someone that close to you makes the world a different place. The desire to go on, obtain goals, and enjoy life goes away. I love this quote:
Losing people you love affects you. It is buried inside of you and becomes this big, deep hole of ache. It doesn't magically go away.
Yes you go on, you continue to function in life, focusing on the family you have left and your lost one's desire to make life good. That's what they would want. My dad and brother would want us to be happy, focus on our children, and laugh everyday.
To my Dad:
My Dad was my mirror, without him I can't see myself.
