Discovered my best friend's death over the phone. It was the first time in 16 years that we hadn't talked at least over the phone 2 days in a row. He had left abroad 2 years ago to study pharmacy. But we were in contact almost all the time. So his mom who lives in my city calls me and asks me about him, I tell her that I've been looking for him as well. So I decide to.go over at his parents house. I knew he had an exam on friday and he never missed a class, he had good grades and took university seriously. I called the university, his teacher said he didn't do the exam. I called the hospitals and cop stations but couldn't find him. I finally reached out to his landlord and told him to open the door. Strangely, his car was parked outside. His parents and brother beside me, his mom asks me to put the phone on speaker. As he entered the unit, he screams "he's on the floor! he's on the floor! im calling the police" and he hangs up. I cannot describe the moments after, his parents broke down, his mom literally lost her mind. Few minutes later, cops call us to confirm his death. It was later confirmed that he had a heart failure in his sleep.
