My dog died earlier this month at the age of 16 and I've been depressed ever since. I lived with him alone in my flat. Over the time he was with me both my parents died and I never got married so I feel like I'm alone in the world. His death has lead to grief but I also realized that as a 47 year old, that dog was my only real connection left in this world since I don't have any close friends at all. I don't see a point in such a life and I feel like I'm too old to change.
