Hello...I Just Lost Someone Very Dear To Me And I'm

Hello...I just lost someone very dear to me and I'm still trying to make sense of all this. He was found lying on the floor with foam at the mouth and a line of blood that ran from his nostrils going across his cheeks, not straight down. What does this mean? He had pneumonia and was taking antibiotics, using a pump, cough syrup, antidepressants. Can you shed some light on this for me, please!
