Yep. Maybe you will fail. Guess what? It's the rare person whose entire remaining life is determined by one day of failure. You are holding on so tight and trying so hard to control your situation, no wonder you're driving yourself *and* your wife crazy.
At the moment, you *do* risk driving her away, at least for now, just so she can get a little peace. All because you have to feel like you're doing *something*. When you leave her alone, you ARE doing something. You are *respecting her requests* as if you actually understand that she is her own person with her own needs, not just an extension of you. Think about it.
