Did you know that I lost another puppy today?
On no I am sorry, what happened?
I accidentally stepped on him.. Now he's dead
Oh my god that's horrible. You're supposed to take care of your pets and keep them safe. How could you be so careless as to step on a puppy!?
I cold bloodedly murdered my puppy.
It is really upsetting that you did that. Not only is it sad, but it's something that could result in legal consequences. I think you should speaking with a mental health professional, as whatever drove you to do this is serious and you need to work through these issues in order to prevent something like this from happening again.
