Cremation of spouse

My wife is set to be cremated tomorrow at 10:00am. I know her soul is departed and she is in a better place, but I got a knot in my stomach thinking that the love of my life is about to be burnt to ash. The same body that slept next to me for 13 years, was lovers with, ate meals with, etc. anyone else have a tough time with cremation or burial? It just seems so surreal. Like a month ago she laid next to me, and I could hear her soft snores as she slept. Now her body will no longer be on this earth. I feel so sick to my stomach and just angry. Curious how you all handled it? 😞
