I was assaulted & need someone to get a restraining order as I fear for my life! Is there a pro bono lawyer who would do this?

I am 65 & am disabled. The attacker is 40. She used a cordless phone to repeatedly hit me in my head & face for 10+ minutes while her parents stood & watched! They unplugged the house phone so I was unable to call 911. The beating was so severe there was blood spatter on the wall, pillows & duvet! My left eye was swollen shut. She had 1 hand on my throat & the other held a pillow over my face. I have been told that a phone is not considered a weapon & that because I didn't lose consciousness she can't be charged with attempted murder? I live in Antioch, TN. Can you recommend someone?
