There are no "correct" answers to any of the questions, and since it's a self-administered/graded tool, there's no guarantee that you won't consciously or unconsciously try to answer a certain way you think would be "better" or more correct or whatever you want it to be. I sometimes take it and "interpret" some questions one way rather than another to see how my scores will differ. That's fine! It's for your use, to let you know more about yourself and how you see yourself as approaching the world. So, no one else can tell you about how you answered except yourself.

Does it "feel" true what it says? Do you see yourself as having the issues that are mentioned? Sometimes it might give us information we aren't aware of and other times confirm that we're where we thought we were, dealing with a lot of stress or old issues or spending too much time online, etc. Taking it every few months might show us if we feel we're getting better or worse, etc.

It's only about you so you can't compare to other people and "how many"; it's not that sort of tool. There's too many factors and this is just about you and what you feel and no one else is you :-) so there won't be other people with your scores.

Bipolar and Borderline Personality Disorder are two very different illnesses. Have you seen a therapist and/or psychiatrist? Like it says, if these issues bother you, interfere with your life, you might want to get some help with them.
