I Am a Born Again Christian

So one of our closest friend's mother died a few days ago. It was sudden but she had been dealing with health issues for years so not too unexpected. Sad situation all the same.

So he gets an angry call from his brother asking why he wasn't at the funeral and friend is all confused because the funeral was going to be next week.

Turns out his other brother was in charge of the arrangements and didn't want our friend there, so told him It's next week and being planned when he had arranged for a quick burial two days after she died. Then told his other sister and brother that friend refused to attend. He then told them friend was in charge of the funeral arrangements and that it was his fault only the siblings and aunt were invited.

Luckily his family knows friend better but it's such a horrible thing for that brother to do.

I don't know how to pray in this case. I personally am hating his brother right now and I don't like hating someone. I know WHAT to pray on, Just not how to get in a better frame of mind before going in to prayer. I don't know why I'M so upset about it as if it was my mother or such either.
