A bit of strategy ........

[Fluvius Camillus]

Retreat all troops from all fronts, land your armies near Pella, take it, enslave it raze every building that can be destroyed (including the royal tombs) then do it again until there are 400 people left. Then leave it to rebel and people will achieve nothing there for ages... Then make a screenshot of the stone age ruins called "Pella" and send it to Maion together with the battle reviews of Cynoscephalae and Pydna

Now for the serious part, could you post a map of your empire, to fully understand your situation?
