I believe negative things that have happened to a person, whether with or without SA, can result in him/her despising that very thing. Its only human nature after all to dislike something if you have had unpleasant experiences with it.
Whether a person overcomes the thing that he so depises will have to be viewed as a case by case basis. It doesn't mean if a person doesn't have SA, then he will succeed in overcoming the negative things that have happened to him, and similarly, it doesn't mean if a person has SA, then he can't overcome the unpleasant experiences that have happened to him.
I think the deciding factor for if a person overcomes his past difficulties is the strength he has within himself. For example, a sensitive person (one without SA), can be put off by negative things that have affected him before and refuse to ever be in the same situation again. Whereas, an SA person with a strong willpower and deep strength within him, though deterred by SA, can overcome negative events, other non social areas of his life and not be put off simply because he had encountered negative experiences from it.
