IMO psychology's aim shouldn't really be to make people "normal," but to help individuals become what they want to become. From my understanding of things, a person can't be diagnosed with a disorder unless this disorder interferes with some aspect of that person's life in an unwanted way. For example, someone may in fact be a sexual sadist, but if this "disorder" or "behavior" doesn't negatively impact that person's life, then it can't be classified as a "disorder." Besides that, if it isn't causing a negative impact, then there is no reason to try to change. So in your particular situation, I'm guessing that OCD does in some way negatively impact your life. Your dilemma however is that essentially the "cure" is causing you to lose your ability to focus creatively. If this is in fact the case, then it seems that your choice of whether or not to continue pursuing treatment for OCD depends on what you value more. Your art or you ability to function optimally. Weigh the pros and cons of treatment and decide from there.
