I got a 17 as well, but I'm in a good mood today. Nevertheless, I've been working hard on boosting my self esteem for years, so I'm proud to see that I'm in the normal range.
At first I scored 18 and that just didn't seem right. Then I looked back and realized that I had mixed up the order of the choices for a few questions. I agreed when I meant to disagree, or disagreed when I meant to agree.
18. I do have social problems, but I do my best to separate them from my sense of self-worth. I think it's important to shoot for that, even if we can't get rid of the anxiety.
