Well first of all I'd say to disregard online tests. Most of them are shoddy at best. Go see a counselor or your doctor. First step is finding out whether you have a disorder or not.
I'm not going to lie, there is still a stigma around mental disorders. That doesn't change the fact that if you have bpd that you should get treatment for it. The more people that start being open about mental disorders the better. People treat them as being different or messed up or wrong or whatever because they don't understand. People understand cancer, they don't understand depression.
I know it might be scary to have to deal with peoples reactions but if you take this first step you can help someone else take their first step. There is nothing wrong with having a mental disorder. Go see your doctor, everything will sort itself out. You'll be alright.
