This is kind of a weird connection but I went to school with a guy who is diagnosed with BPD. 

Him and I both have dark hair and kinda slightly tan skin but have extremely pale siblings with strawberry blonde hair.

We are both raised by narcissists who are very very controlling and the scape goat kids. Our parents are both extremely hard on us but we both have more bubbly/excited personalities and adhd. We both have siblings who’s really “perfect” strait A, extremely high achieving students.

Our parents work for the same company.

I am a shy person but he’s very outgoing. He kind of had a “trouble” reputation in school and was known for being funny. But it was obvious that he’s very sensitive and emotional deep down. I’ve always been sensitive/emotional and I feel like he is too but we come from very cold, unemotional families 

I am not diagnosed with BPD but show a lot of traits and will go to therapy soon but I just thought the connection was interesting
