Ok so I know there are quite a few insomnia threads on here but I am really worried that I might have fatal insomnia. I haven't slept for the last couple of nights but my sleep has been bad for a while now and I am freaking out that I will never sleep again. The wierdest thing is that I don't even feel that tired but I know I have definatly not slept. I am scared that my brain might be getting used to not sleeping. I have work on Thursday which is just voluntary for 3 hours but I am scared that I will start hilucinating or I will collapse while I am there. I know how unlikely fatal insomnia is but what if I am the unlucky 1 in a billion that gets it?
