major diagnostic BPD symptoms that she exhibits:
1) Intense, uncontrollable emotions/poor emotional affect regulation: crying uncontrollably like she is in this video (she's also done it a few times on younow, had a total breakdown), she's mentioned (and Becky confirmed) intense anger when she doesn't get her way. This symptom is basically snapping from fine to hysterical or the other way around in a split-second, or being stuck in a specific emotional state for several days. It's not limited to being angry or sad, it can include overwhelming jealousy, intense happiness/euphoria out of nowhere.
2)Suffering with at least one compulsive destructive habit that effects quality of life (the list can include drug addiction, gambling addiction, compulsive spending/eating, self harm, etc): she has several. compulsive shopping, compulsive overeating, hoarding trinkets, she's also mentioned that she compulsively picks at her scabs.
3) A shifting/unstable sense of self or a lack of an identity: She's a shell of a person with no substance and has no defining hobbies other than her compulsive habits. She mirrors the personalities of the people she spends the most time with, changing her accent and her style of dress with each relationship. With Kasey she was an edgelord (her old facebook is a shitshow). With Krystle she was a shy, quiet gorl (and stuck to a diet, losing 89 elbs because Krystle was on a diet). With Destiny she became a louder, brightly colored goof with a pebbles flinstone bow. When she first met Becky she started wearing her hair down, all black clothes and speaking with a hick accent. People with BPD are often chameleons because they think that's how to get people to like them, either by mimicking their personality or becoming the exact type of person they'ye looking for.
4)Intense/unstable relationships, often with a pattern of idealization/devaluation: falls in love immediately with every girlfriend, becomes best-best friends with someone too fast only to cut them off/hate them later over something small. Rafe is a really good example of this. Remember how much AL loved her at first? Then Rafe didn't want to let her eat spaghetti and AL flipped her lid, made Becky stop talking to a friend she'd known for years over literally nothing. The Rafe thing escalated and went back and forth but it began with AL being butthurt over not being welcome to eat someone else's dinner.
5) Suicidal behavior/ideation/tendencies: she was hospitalized as a teenager for threatening to kill herself. Only AL really knows how deep this one goes, but a high percentage of people with BPD are hospitalized as teens for a suicide scare.
other minor/non-diagnostic BPD traits that she exhibits: chronic over-sharing, poor hygiene, history of meltdowns on social media, vacillating between self-hatred and over-inflated self-confidence, LYING (this is a huge one), blame shifting and gas lighting her partners, accusing other people of her own misdeeds (projecting), a lack of true empathy, treating pets/partners as objects she can possess, attention seeking, making excuses for absolutely anything, inability to handle change, being manipulative, making up illnesses and ailments, spotty work history/inability to hold jobs.
People with cluster-b disorders are essentially stuck in a teenage level of emotional maturity for their entire lives, and the vast majority of them don't think there's anything wrong with the way they behave. Self-aware cluster-b people are rare, and that's why the recovery rate is abysmally low. Unless AL recognizes that she's the problem, decides to go get a real diagnosis, enrolls in a structured behavioral therapy program (and sticks to it) she will never change. It takes serious commitment and years of CBT/DBT to see any meaningful improvement in life functionality. She's just going to whine about it, self-diagnose, continue to behave this way, and eventually Becky will come to her senses like all the rest of her GFs and dump her. I will be really proud of necks on that day. As infantile and simple as Becky is, she seems like a nice person and doesn't deserve to be treated the way AL treats people.
Sorry for long ass :autism: I've gone through the lengthy and painful diagnostic and treatment process of a family member so I know a lot about it. People with this disorder behave eerily similarly to one another, almost like they all read the same handbook on how to act.
