Unreliable
At some point in the last several years, I became unrelaible. I have the sense that I used to be admirably reliable (someone will jump in, no doubt, if I'm wrong), but that is definitely not the case now. I'm very sad about that.

I've had the same horrible sensation. I think it comes from being a parent and having to realign your priorities to fit with that.
In the sense of punctual, always on time, doing-what-you-said-you-would-when-you-said-you-would I think I get your point. That's the kind of reliability we expect and enjoy from machines.
However, if reliable has the sense of trustworthiness, of being-there-for-you, or of getting-the-job-done-somehow-in-spite-of-all-life's-unpredictability-and-craziness, then I would say you're probably doing just fine and better than most. Parents get real good at this and are generally much better for it.
When I need someone to dress in women's underwear, climb on a garage and sing 'Ride of the Valkyries,' I rely on no one else.
