Generally speaking, if you struggle with consistent intense internal and external conflict in your interpersonal relationships, have consistent intense feelings that cause you distress, angry outbursts, and severe issues with self image, it might be what you are dealing with. The only way to know for sure is counseling, which I highly recommend. Because it is initially difficult for someone to realize their feelings and reactions are not rational, and difficult for those without it to understand what it is like compared to “normal” feelings, I would strongly advise against self diagnosing. A counselor/psychologist can help you work through if your reactions to things are rational and give an objective view on whether or not you are displaying the symptoms. Finding a mental health professional who is a good fit for you and who provides Dialectical Behavior Therapy is a game changer. I am diagnosed with Bipolar Disorder but struggled with many of the symptoms of BPD when I was younger and DBT gave me the foundation to change my thinking patterns. If you are unable to access professional help at this time I would recommend getting some DBT workbooks to help you in the meantime, I personally think it’s a form of therapy that pretty much everyone can benefit from. Good job on being proactive with your mental health 💕
