Although you don’t want to admit it, your symptoms do interfere with your life. You are fearful of developing relationships. You were depressed for years after one break up and passed out after another. You say you are generally over-reactive and actually got suicidal when someone tried to do a good deed by cleaning your house. Although you are able to function at work and school and your basic self-care seem fine, you aren’t able to cope with social interactions that don’t go the way you thing they should. So, yes, I do think something may be “wrong.” So do you.
Please remember that online self-administered psychology tests are intended to be used for education and guidance only. They are not intended to be a substitute for in-person evaluation by a licensed mental health professional. A self-test can indicate that perhaps you should have such a professional evaluation.
Personality disorders are particularly difficult to assess on a self-test since there is a significant overlap in symptoms for a number of them. It’s also unclear whether the “test” indicates a mental illness or a lack of sufficient coping skills that can be caused by any number of reasons.
The best way for you to get your question answered is to go to a qualified mental health professional for a professional assessment. (Most schools have such services available.) An assessment will provide you with a diagnosis based on clinical judgement — or will reassure you that what is needed is coaching and support in developing some better social skills. You have nothing to lose but a few hours of your time. You have everything to gain by having a better understanding of yourself.
I wish you well.
