Sounds like the speaker is sifting through new issues in life, where ordinarily she was able to deal through it on her own. But now, she's sensing that grace (whether religiously, from God, or rediscovering her own inner strength) is something that she could really use. She's taken it for granted in times before ("well you say you don't need this right now, just throw it out"; "i watched grace pass me by"). She also realizes the limitations she has in adding to this grace ("you can't feed it"). And as she's pacing back and forth on the bathroom floor, ruminating, that's when grace is likely to appear.
