There's nine diagnostic symptoms, you need to hit at least five of them to even be CONSIDERED for a diagnosis. And yes, I would know, because I just had a full psychological assessment done the start of this year and PROFESSIONALS diagnosed me.
I'm sorry I know getting an assessment done is a privilege and can be expensive but I'm so sick and tired of these 13-16 year olds self diagnosing themselves with BPD, like it's a tricky mental illnesses to diagnose because of all the co-occuring symptoms and illnesses.
And not to mention the fact that they're all teenagers???? Your brain is still developing, mood swings, not wanting to be abandoned, relationships falling out, etc etc is part of being a fucking teenager. It's common for these to occur.
