Anxiety attacks

My child’s father and I don’t really communicate because of his actions and him not responding. He asked to see my daughter and I agreed. He hasn’t seen her since she was a couple weeks old and she is now 4.5 months. Whenever he text me or is even mentioned I get terrible anxiety. I feel like I’m going to throw up , my stomachs hurts really bad, I get hot and start to sweat. It’s the most uncomfortable and sick feeling I’ve ever had, if I’m eating I can’t even finish my food. I don’t like to be around him by myself because I’m not comfortable. Not that I’m afraid but I’m uncomfortable. He has a temper and can’t control his emotions and that also has me nervous. Hopefully everything goes well when he comes to see her but I’m extremely nervous and can’t shake this sick feeling. Ready for the day to be over already.
