Help cremate my sister

My sister Heather was only 36 when she got her wings this morning and I’m at a loss for words they think it was heart failure or something to do with swelling due to her size but I’ll know more this week when they do their exam. Heather was such a sweet and kind soul and everyone that knew her loved her. If you could donate or share it would be greatly appreciated because my heart hurts so bad. Thank you from the bottom of my heart
