>What was so wrong with her life that she was vulnerable to the witch?
In the PSP game(Not the joke timeline where yurifags spread misinfo about Hitomi) Hitomi is shown more affected due to Sayaka getting closer in the Hospital for Kyousuke, Madoka notices that.
Even without the PSP game is logical that Hitomi was suffering because she knew that she or Sayaka would be hurt anyways due to them loving the same guy.
Kyousuke loves music, he had more things to worry about than girls at the moment.
