In brief: Borderline
Diagnosis of personality disorders is not given before age 18.
You might have the traits, if symptoms of borderline exist & are pervasive.

By definition personality disorders can only be diagnosed in patient 18 and older, however a 12yo can certainly have similar behavior , and if it continues may likely get that dx.
Treatment is best sooner rather than later.

In brief: No, but...
Personality disorders typically are diagnosed only in late teens and adults, because many of the symptoms are common in younger individuals but then go away.
If you are having enough troubles that you are worried about having bpd, talk to a school counselor or ask your parents to let you see a mental health specialist. It means life is overwhelming for you, and you deserve to get some relief.

In brief: No
Borderline personality disorder does not get diagnosed in those younger than 16 years and even then less likely for teens 16-18 years in general.
The teen years do involve the development of identity, emotional development and growth, and personality exploration.
