I've been having a very bad headache for a week now. It was significantly worse yesterday. I haven't eaten regularly. Now, I feel very strange in my head. I've never been high but I imagine this this what people who smoke weed must feel like. I feel lightheaded, which is very strange because for most of last week I couldn't get out of bed. Lying down was the only position I feel most comfortable in. Even now I feel my vein popping in the back of my head. It's a torment. I just watched something on TV and I can't stop laughing. It's hysterical. Nothing's funny and I don't feel like laughing but I can't stop, Is it because my headaches are starting to get better? Or is it symptoms of something worse? I should mention that I just discontinued SSRI and benzodiazepine drugs two weeks ago and I haven't felt right in the head ever since.
