The problem with this is that she's talking fluent gibberish. She can grumble about how the time lost raising her made her 'career' at the library go away until she dies but the plain fact is that her alleged job was going to go away child or no child. This means that she can blame computers for it just like she was going to blame them for her not finishing her schooling after the fact. As for her travel plans, it really doesn't seem likely that she'd want to be away from home for more than two weeks a year and she does that anyway so that's another thing that April really didn't ruin.
Another thing that she didn't do is fill Elly up with a free-floating feeling that she'd somehow or other been cheated out the good life. Ol'Flapandhonk would be saying that it sucks to be her if her house had been empty since 2004. The only real difference is that John would be asking "Uh, El? Why are you blaming someone who doesn't exist for not existing? Isn't that like saying 'Whatever kills me makes me stronger?'"
