Funeral arrangements for my dad

Everyone knows my dad meant the whole world to me.. my life revolves around making sure he was always okay. I’m going through the funeral arrangements alone and it’s very overwhelming because everything is going on too fast. If anyone can help me share this or donate anything.. it would be greatly appreciated. My dad was such a good man and I wish he could have lived a better life but he was sick almost all his life and it hurts us all to know he’s no longer with us. I wasn’t aware that everything needed to be paid in full and I don’t know where to turn for this because it’s a lot right now for me.
