Hi and welcome to the forums
I did the same thing the first time through and she was TOUGH.
Try and remember what powers you gave her, she'll use those on you. Obviously buff up and use speed. You can search the forum for tactics. ***SPOILER***
I backed away and fought the lightsabers one at a time. Once they were done I went after Traya. She resisted force powers, so I buffed myself and used my lightsaber. Even then I had to strategically withdraw(run away) and heal myself several times.
I hope this helps.
