It sounds like you are going through difficult times. Borderline Personality Disorder (BPD) is characterized by a pervasive pattern of instability of mood, interpersonal relationships, self image, and marked impulsivity. To make a diagnosis of BPD, five or more of the following must be present: recurrent suicidal behavior, gestures, or threats, or self-mutilation; inappropriate and intense anger; intense and unstable mood, chronic feelings of emptiness; unstable self-image; alternating between extremes of idealization and devaluation in interpersonal relationships; frantic efforts to avoid real or imagined abandonment; impulsivity in sexual activities, spending, reckless driving, binge eating, or substance abuse; and transient, stress-related paranoia or severe dissociative symptoms.
Some people have less than five of these criteria, and may be regarded as having borderline peronality traits, without meeting criteria for BPD.
Adjustment disorders are defined as emotional or behavioral symptoms that develop in response to identifiable psychosocial stressors. They may be associated with anxiety, depressed mood, and/or disturbance of conduct (e.g. fighting, reckless driving, or vandalism).
I am not familiar with Army regulations, but will encourage you to discuss your concerns further with your behavioral specialist and psychiatrist.
