Feelin for ya.
My mother, who actually can be at times rather nicely caring, can REALLY DRIVE ME CRAZY too!! Sometimes really lacking in supportiveness, sometimes selfishly reactive, sometimes just stupidly annoying ...

But, as I guess seekersinking is kind of saying, these mothers of ours - like most people - are just struggling along with whatever they've got (and haven't got) trying to make their way through this crazy world.
