I get very narrowly focused on 1 or 2 subjects so intensely that it can lead to physical pain. Then I finally break the cycle and think in a whole pattern again, without the intensity of the subject matter. I can break away, but it takes a great deal of refocusing my energy. When I get pulled into a topic- such as cluster in which I am interested, all I can think of is that particular subject (or maybe a counter subject) and nothing else. This is very distracting to me and it can cause depression and anxiety because I want to know so much about that subject, but I find myself either defending a cause or trying to figure out my true intentions (politics and history are much of the root of these issues).
Examples: I get stuck on Country Music, The South, WWII, my physical appearance, Jews, contemporary politics, etc. When I get stuck on these things they don't bring pleasure, but they bring pain because of the polarizing opinions therein.
If someone says "I like all kinds of music, except Country". I want to defend Country Music with passion and vigor and explain to them how important it is they at least give it a try. I know these are opinions. They ruin the whole musical experience for me when people polarize a certain genre: i.e. Country, Folk,etc. I have a desire to be right! I will start asking random strangers if they love Country Music? Why shouldn't they love it? Then I talk about Country Music incessantly. I am supposed to enjoy country music, but I can't handle opposition.
The irony is, intense subjects usually are pleasurable. I have those too- such as music and hobbies I enjoy . But these are topics in which I get intensely heated about, maybe because some of them are contested.
Does anyone else get this cycle of subject interest that comes and goes?
