I am so tired

And I don't mean sleepy.  I mean worn out, worn down and DONE.  I feel like I am the only person who w ants to figure out how to deal with my child.  And I am beating my head against a brick wall to trying to get somewhere.  No one seems to be in agreement with me and I feel like I am trying to do it all alone.  Not only alone- but in opposition of her father.  He says things like "maybe she needs help; maybe she needs meds", then when I pursue help, he won't even talk to me.   If nothing else she does better with consistency and discipline.  I tell her she need to do XYZ before she plays outside.  I go to the grocery store and when I return she is outside and XYZ is incomplete.  Because he "forgot".  I am so frustrated.....
