Turn your Bible to the book of Psalms and begin reading, or listening to it if you have Bible CD's. The authors of these verses experienced what you are experiencing now, fear, anxiety, also depression , panic attacks it seems. Read how God helped them through this, and how they, in turning their thoughts to him, and praising him and his omnipotence, and trusting that he would help... found peace within, and found many ways to praise him. Also, if you have hallucinations, it may be helpful to get a dog . If it is only a hallucination, the dog will obviously not react to whomever you think is there. And if you have not yet gone to see a Christian counselor, please do so as they can pray with you, and evaluate to see if there are medications needed in your case, to help with this. I will lift you up daily, for your peace of mind, and your complete healing. Reading Psalms, having a good support system (loving family or friend), and praising God constantly, has helped me through a similar episode in the past. But if there is also a chemical imbalance at this time, it may warrant some medication in your case. You will be in my prayers constantly. Please let me know when this is resolved.
