You're being gaslighted.

 

You should not allow her to make you question your sense of reality.  Next time, do not react, and just do what needs to be done.

You are depending on her in order to feel your sense of worthiness, and she is exercising her power over that dependency.  The more she de-values you, the harder you work to prove to yourself that you are valuable.

She believes, factually or not, the things you make her do are for your sake, and she needs some compensation for her effort.  She relishes in seeing your "tortured" reaction.

Remind her that your effort is for her own sake, and how fortunate she is to have people who love and care for her.  There are not many years left before she has to step into the jungle by herself.  Treasure the time together.
