Hi
I was just wondering, do I really have to work with my supervisor. she is not very helpful and extremely unapprochable, I can't change supervisors at this stage, my dissertation is due in September. I'm supposed to send her draft of any chapter am working on but I can't stand her. Long story short, Is it mandatory to work with your supervisor?

Hi T_89 - in short - no.
If you want you can complete your dissertation and hand it in - in September without speaking to her again. She is there to guide you. It's rare that a student does not want that guidance normally they complain of their supervisor being unresponsive.
