Hi, my name is Senada, I live in Sydney. I'm 42 years old. I am currently suffering from dizziness, fast heart beat, headaches and feeling as if I am going to pass out. I am scared to be left alone and un attended due to the way I'm feeling. I have consulted doctors and had a CT scan of my head and still no result. I am going to be under going a MRI scan this week, I have never done this before and I am feeling very scared and I am afraid if I have a panic attack as I am undergoing it. My GP thinks that i suffer anxiety and panic attacks and prescribed me lexapro and valium. Could you please offer me any advice about the condition I am in.
