Wiccans is it a bad idea to?

Hey guys need some help, as most of you probably know I am a newer Wiccan and need some advice. Well last Tuesday, something tragic happened to me, someone forced entry into my home and tried to attack me. I am physically ok but not emotionally, or psychologically. I have read in several books it is not recommended to do rituals while you are sick. (not sick but huge amounts of stress and anxiety) But I was thinking casting a circle and doing a relaxation ritual may help me. BUt not sure if my intense anxiety could effect it. Any thoughts or suggestions? Thanks.
