Obsessive-compulsive disorder - This is, according to The World Health Organisation the 10th most disabling illness and one of the hardest to diagnose. People with OCD have weird thoughts which they find really difficult to ignore. Most having trouble throwing junk away, disturbing sexual and religious thoughts and worry about the order things are placed. So Just for a laugh we have filed OCD under 'K' in our A-Z! To overcome these desires suffers carry out pointless routines such as washing, checking, counting, cleaning when it isn't necessary. Most OCD 'ers realise their actions are pointless and they are one step away from a mental asylum, trouble is because they are conscious they're being freaks this damages their self esteem and can lead to depression. Hopefully this explanation was useful and as easy to understand as A C B, sorry A B C. By the way, we used to know some jerk who had OCD, unfortunately he started to annoy us so much we washed our hands with him. Five times a day in fact!
