she's feeling guilty as fuck cause she wasn't there when it happened. my dad was alone and he has had a heart attack before like 4 years ago, then 2 years later he had kidney cancer... she left him for the weekend to spend some time with her family. This happened and now she feels guilty about leaving him sick alone at home. This is probably going to be hell for her.. she never got better after her depression this is just going to add to all of this.
