I looked it up again: As far as serotonin receptors are concerned, Abilify is a partial agonist at 5HT1A and an antagonist at 5HT2A, 5HT2B and 5HT7. With dopamine it will selectively bind to D2, however there is evidence that rather than "partial agonism", its action might be best described as "functional selectivity" - it will act as an agonist where dopamine is too low, and an antagonist where dopamine is too high.
It's not really a "dopamine booster" except at neurons where dopamine is very low, as far as I know. There are cases where abilify has induced parkinsonism, so that would suggest that generally there is more blocking than activating going on on average.
It is certainly a drug worth trying, and it may very well help with your anxiety, just probably not in the way you think (i.e. it won't boost your dopamine to the point where it counteracts your serotonin, especially since it is also a partial agonist at the 5HT1A serotonin receptor).
