Lost my best friend and roommate

We met 3 yrs ago when I moved to FL to care for my dad as I was going through a divorce after 27 yrs of marriage. He was living next door with his parents and pretty much to himself. I keep saying hello just looking for a friend, We finally started chatting and became thick as thieves. He was 20 years younger but we still hit off. He and I would laugh and cry about everything. Helped with my dad and when my dad died he "took are of me" . He was a jack of all trades and we remodeled the whole condo and he stayed with me (as friends-he had his own room). I needed him and he needed me. Last Friday I woke up before him and when I came back after walking the dog, I found him in his room on the grpund with blood over his nose. I called paramedics but I knew he was gone. Now I can't stop the tears and I don't know how to move on. I just want to be with him
