I've suffered from this fear my whole life. I find it manageable most of the time. This past week or two though things have been out of control. I don't know what it is. I can't stop obsessing about getting sick. It seems like I talk to someone every single day who has been sick recently and so I'm constantly paranoid that I'm going to catch it. I know it doesn't make sense, I know it's irrational, I do my best to take care and be careful, but it's just all I think about. I feel totally doomed. Why can I cope usually, but right now I just can't? I can't even sleep. I really wish I knew what to do.
