I’ve spent my entire life sacrificing myself for my children and now those (damn bastards) have hidden away my cigarettes If the sacrificing had been done para mis hijos, the general meaning would remain the same, but the listener would have to come up with the implicit verb, which might not be obvious in this context.
Here is a better example of the latter: Llevo toda la vida sacrificándome por mis hijos y ahora los muy malditos me han escondido los cigarrillos.
