My dad this morning

I am deeply saddedend by my dad's reaction to me this morning.  I asked him to lower the tv and he was complaining about life and how disgusting it is and he is fed up of this life... as if saying that asking him to lower the tv will affect him to end his life.  It is an over reaction I realized but it is so scary to hear that from my dad and it makes my mood go down.  Is it that big of a deal to ask him to lower the tv?  I have no idea.  I just wanted to write it down so that I do not forget it and come back to it later.  It sucks.  I hope that I could have nip it in the butt and got done with it.  But I was too afraid to talk to him about the incident.
