Though it sounds like this was an episode rather than a life-long issue -
This morning for some reason I began reading about Ted Kaczynski's psychological profile and I ran across
this:
While at the University of Michigan he sought psychiatric contact on one occasion at the start of his fifth year of study. As referenced above, he had been experiencing several weeks of intense and persistent sexual excitement involving fantasies of being a female. During that time period he became convinced that he should undergo sex change surgery. He recounts that he was aware that this would require a psychiatric referral, and he set up an appointment at the Health Center at the University to discuss this issue. He describes that while waiting in the waiting room, he became anxious and humiliated over the prospect of talking about this to the doctor. When he was actually seen, he did not discuss these concerns, but rather claimed he was feeling some depression and anxiety over the possibility that the deferment status would be dropped for students and teachers, and that he would face the possibility of being drafted into the military. He indicates that the psychiatrist viewed his anxiety and depression as not atypical. Mr. Kaczynski describes leaving the office and feeling rage, shame, and humiliation over this attempt to seek evaluation. He references this as significant turning point in his life.
