SG, if you were to surprise Mom by making her a cup of tea,
or get her a warm blanket when she sits on the couch,
or pick up a blossom for at the florist, or something like that,
I'll bet it would do one of two things:
Either it would break the tension and smooth things out for a while,
Or, it could make Mom so frustrated you'd have the satisfaction of one-ups-manship.
Either way, your own day could be little better
P.S. If it works, don't do too often as Mom will come to expect it,
and get ticked off all over again.
