I also suffer from OCD & counting is my #1 compulsion. I count almost everything. For example, everywhere I drive I will count every telephone poll which I pass. If I pass 37 on my way to work, I must pass 37 on my way home. All poles passed when going somewhere are considered positive; therefore, all poles on the way home are considered negative. Their sum must be a value of 0 for me to be able to go home.
I also count lights, carpet patterns, stairs, & even the number of hairs on my own head. This becomes very debilitating after a while; however, I am learning how to fight my compulsions through CBT (cognitive behavioral therapy).
I suggest that you consider seeing a doctor, if you haven't already, before things get overwhelming for you. Good luck & don’t worry about counting the words… already did! There’s 150.
