I have been diagnosed with Bipolar 2 and am currently taking lamotrigine. I feel like I have a lot of the symptoms of BPD (volatile emotions, hella insecure, splitting, etc). My therapist says that the exact specific mental illness or label doesn’t really matter as much as processing my feelings, developing coping mechanisms, and finding out what causes them but it feels like it would be easier knowing wether or not I’m Bipolar or borderline.
