Occasionally i'll get a migraine. This involves nausea, high sensitivty to stimulii, most notably light and sound, and extreme pain. All of this usually force sme into a very dark, quiet room where I curl into a ball with my hands over my eyes and head where I wonder about what the world would be like if I died.
Now don't misunderstand me here. I'm in no way suicidal ever. It's just that in those moments I wonder how long a body could handle such extreme pain without the head imploding.
