Yes, as a therapist seeing someone become very upset is normal. You are talking about something horribly painful. Crying, becoming angry, and other strong emotions is expected. Therapists know that is the nature of what they do and understand when a person feels upset. Most therapists are empathetic and understand. When I have had someone cry or get upset, I feel sorrow and empathy. Your therapist probably feels the same. She most likely sees many people cry and besides feeling empathic, she doesn't think anything of it.
Thank you. I feel a bit better about the situation but still very nervous to have to speak about it. But I really want to get better so I will sometimes have to push myself.
That is ok. Voicing your feelings often means confronting them. It makes it more real to you. And it also makes it more real telling someone else. You are right, you will get better by giving a voice to your feelings. Sharing what you feel takes a burden off, even if you think you feel better keeping it to yourself. It is the fear that prevents you from getting better so confronting the fear is a very good step in your recovery.
