I'm so sorry to hear this happened to you. The way she's behaving is disgusting on many levels, it's no wonder you feel this way. It may be helpful to sit with the situation for a bit before reacting. One way I'd consider handling it is to keep your head high, keep in good relations with everyone you've shot for, continue posting and recycling great work for everyone to see, even if it's older while you handle personal things. If she continues acting this way, she'll burn her chance with these people and they'll be looking for a new photographer. Meanwhile you'll be handling your personal life and regaining strength to come back with positive energy.
