annoying

I have one person that insists i tell her everything, but when i do, she doesn’t know what to say to me. She doesn’t understand why I feel ab certain way or why i behave a certain way. Its so difficult to try to explain things to her and then she gets mad because i don’t give her a good answer. I can’t keep telling her things because i can’t explain anything and she doesn’t want to listen just interrogate me and i cannot stand it any longer.
But i don’t know what to do without her… i am too dependent on her to just let go of her. I hate having to be dependent on other people. But i think i might need someone to be dependant on but i am unsure if it should be her or not.
i don’t know… my mind is so messed up i can’t think straight.
