Hey I am a 22 year old male, I weigh about 65kg. I have an extensive history of anxiety, particularly OCD, and have obsessed over many varied topics in the past. At the moment however, I obsess over leukemia, and other cancers sometimes. Also, sometimes heart attachs or cerebral aneurysms rupturing. In addition to the anxiety conditions, I have a history of substance abuse that may exacerbate the feelings. Also, I notice coincidences quite frequently that seem to relate to my concerns and then cannot stop thinking about them.
