Separation Anxiety, part deux

Lately Z has been.. very very very TWO.  I know, it's what they do at this age, scream bloody murder, throw fits, exert independence, it's development, it's good, well, for him anyways.  For mommy?  It sux, big hairy ones.  He now demands to get OUT of the shopping car in Target, umm.. exsqueeze me?  Nothing better than a toddler "helping" push the shopping cart around Super Target, between that and the 36 trips to the potty no expedition to Target is less than 2 hours now :p.  At the same time he exhibits this obvious *need* for independence, he is getting more clingy, for the last week, for me, trying to leave for work has been a nightmare.  He clings to me like a leech and screams "no go work mommy!  Sit down, stay with me!"  *le sigh* Yes baby, I would *love* to stay with you, trust me, most days I agree with "no go work", unfortunately, I like this thing we have called a roof, and that fridge, well that shit ain't free sweetheart, and you eat like a horse, so mommy's gotta "go work".
