Sorry to hear, man. I know losing a parent inexpectedly hits people hard. A long time family friend passed away last year due to a drunk driving accident. It hit her kids really hard, and everything kinda went to shit for them for a while. Hell, it even had me confused, and we weren't as close as others. Just thinking of not seeing them as usual feels weird at first, but you'll get past it. All you can do now is do you and do what you feel would have made them happy. Good luck, man.
