(((Choublak))) - I'm so sorry you are going through this. My dad has mentioned similar things over the years I've been back at home, the most recent was last week when he had thought about driving off a bridge.
I know he's not serious, but I don't know about your dad. My dad wants attention, but this time I snapped and made him walk it through...who would have to identify his body? Me. Who would be left cleaning out this house, the one he, mom and I built, so it could go into foreclosure? Me. Who would be left wondering what I did wrong, what I didn't do, etc. for the rest of my life? Me and everyone who cares about him.
I don't know if that would help with your dad, I just know how hard it is to hear from a parent
Big hugs and prayers,
Amy
