Yep. Funerals suck. Unless you're getting laid by a second cousin in the cloak room of the funeral home, there's no possible way to make them NOT suck.
And the more funerals you go to, especially for close family members, the more they suck. By the time you're in your thirties, you'd rather get your teeth pulled than go to a friggin' funeral.
Sorry about your loss though. It just ain't right to lose your dad in your twenties.
