<human>: My mom died about a year and a half ago, and my dad has been completely broken ever since. He constantly denies that anything is wrong, but it's obvious by how much worse his co-dependency has become. He's always searching for relationships with fellow AA members, or (his most recent love-interest) people with debilitating physical illnesses.

His way of handling stress is to completely ignore his problems. He's done this with his house (he lives by himself on 5 acres of land that is molding and deteriorating from neglect because he can't take care of it by himself), with getting rid of my mom's cats, and even with burying my mom. He puts it off to the point where I have to eventually do it myself.

Currently, I'm suffering from a lot of anxiety and stress myself because of my mom's death, and this certainly does not help. In fact, my anxiety has considerably increased since I've been trying to help my dad, which has been about a year now. None of my other siblings are helping him, nor are they telling him what he needs to hear (i.e. that he needs to seek grief counseling, and stop ignoring his problems). 

He won't go to therapy because he doesn't believe that anything is wrong. I don't know how to help him, and take care of myself at the same time.

<bot>: My dad's way of dealing with stress is to ignore his responsibilities until I have to intervene and take care of them.
