Insomnia itself actually explains two of those factors. When you don't sleep for extended periods of time, you physically don't have the energy reserves to concentrate. Likewise, it can also cause the characteristic dark bags under the eyes, which those yellow marks under her eyes are basically showing.

The obsessive behavior cannot be explained by poisoning. Plain and simple. In fact, I'd be inclined to say it's a side effect of the inability to concentrate - she's so driven to defeat Torchwick that she's shunting all of her available mental resources into it.

Also, if she's not sleeping and taking very little time to do other things, what makes you think she's eating often enough for poisoning to actually work? If she collapses, then there's numerous other explanations - exhaustion or a panic attack as some examples. I don't accept the idea of poisoning - it's the wrong symptom set.
