If someone commits aggravated battery and the victim chokes them in order to restrain the assailant, is the victim able to be punished??

A family member, the assailant, took a 12"+ screwdriver and attempted to stab said victim. The victim proceeded to try to restrain her, to prevent a stabbing, and ended up choking the said assailant, until they stopped swinging and fighting back; This was after other restraint methods were attempted. Now, the assailant is trying to say that it was attempted murder, even though she was trying to stab the victim with a screwdriver (she also attacked first, multiple times). The victim did not hit her or beat her; Their only intent was trying to restrain her because she attacked someone, within the home, that had just gone through surgery and entered the situation unknowingly, then the assailant proceeded to attack him, the victim. We have filed a police report but have not yet pressed charges due to circumstances with family; This assailant denied any involvement to the police officer, yet has expressed to her family that she was choked. (This is also recorded on an answering machine).
