Welcome Catherine,
In terms of being overwhelmed, there's a subjective and a realistic component. Somebody describing the feeling as being like a cup of tea, which keeps gets poured until it is overflowing, but continues to pour, causing that feeling. What I ask myself is what can I control, to minimize that stressful flow of tea, so I don't feel awash with stress? You certainly can't dismiss the cries of a child, and bills, but perhaps some things can be postponed. I have to clean too, and feel disappointed with myself about missing this, but there are other priorities. If I can be easier on myself, the stress can be reduced to a trickle, or something I can manage, using whatever resources make sense to use...From here we can just pray for you...
