I also tend to obsessiveness, Tegan, but mine manifests itself in extreme tidiness and a need to accomplish anything I set out to do. When I first started serious walking, I would decide to walk for two hours and if I got back to the car in 1 hr. 55 mins I would walk around for another five minutes. (Two hours might not seem long for a walk, but these were up extremely steep, rough mountain paths, often involving some climbing).
Now, I just find that if I set out to reach a summit I can't give up until I am there.
I have to deal with letters or phone calls, especially difficult ones, at once. and I have to wash up immediately after a meal. I need as much order and structure in my life as possible, perhaps because the addiction of somebody else has caused me great pain and there is nothing I can do about it, so I control as much of my life as I can.
I don't think I have an addictive personality. All the years I lived in Monte Carlo, I would spend 100 francs, which was then £10, every week on the fruit machines. I would play until it was either all gone or I had won 500 francs, which happened twice. I was never tempted to spend another 100 francs once my money was gone and I regarded it as spending the original stake, rather than gambling it, as I knew I was almost bound to lose it but it gave me some pleasure while it lasted.
I have never smoked or taken drugs, and I drank too much to escape from a difficult situation - until I realised that not only did it not help but also made it less possible for me to cope.
I do believe there is a genetic tendency to addiction but some people overcome it.
