You have already gone more than the "second mile" with your daughter. You are not expected to give all of your resources to one individual. There is need for balance.
More than that... sometimes what the kids really NEED is for us to NOT do for then - because then they don't learn how to do for themselves. You are not turning away from need, but from a situation where to be involved only further entrenches her in the wrong mind-set. It is 'help" but it is worse than NO help, if you know what I mean.
To turn away because you want to preserve a "nice vacation" or "new car" type of thing, would be wrong in my opinion. But to turn away because you need to survive, or to turn away because helping is really hurting... is NOT wrong.
