Cracked in the Head

Sometimes I feel like my brain is a hamster on speed... Like right now, for instance. I've been awake for the last 20 hours, am still wide awake despite less than 5 hours sleep last night and the ingestion of more sleeping pills than can possibly be safe... Here I sit, brain running in circles, like a hamster in a squeaky wheel. This must be what going absolutely, totally fecking mad feels like...
