Don't worry you are not a bad daughter. But the thing that you should understand is, how the world works. If you do good it will return as good, if you do bad it will return as bad.
How to identify the good and bad? If you do or think something which will arouse raga (greed, sensuality, desire),dvesha (hatred, aversion, anger, hostility, ill will) or Moha (ignorance, bewilderment, confusion, stupidity, delusion) then it's a bad thing. This is according to the core buddhism.
As a daughter what you can do? Do what ever you want but always try not to arouse raga, dvesha or moha.
The most important thing you should do is if you pay mother, the aarya (noble) maithree it will do the best for you and her. And I've seen many people have get the successful results out of this, including myself.
How you do it
Daily 20-30 mins (if you can do more then do) think this to your self (close your eyes as it helps to concentrate more). You and your parents may attain Nivana (enlightment). Wish this so deeply. Add what ever the necessary facts like things they do good for you and in return you are wishing them Nivana. As Nivana is the only place anyone can get the ultimate happiness. So basically you are wishing them happiness, no matter the way you get treated.
And as mentioned by Buddha if anyone kill a parent its going to be very bad karma (anantarya papa) that can't get escaped. When someone eat poison with or without knowing that it is poison he is going to suffer. Like that the nature is dangerous no matter we know it or not it behaves the way as it supposed to be. So only thing we can be happy about is Nivana. That's why wishing that (the best thing in this universe) to someone who treat you unpleasant will return you good things.
Believe me, this will make you and your mother's life better. To get results you might need to do this one to two months. (And do not stop there keep continuing...!)
