I've thought I had short term memory loss even tho I'm only 17 but recently I have been doing little stuff like picking up a glass and forgetting when I did it or forgetting which task. And sometimes I become a blurry person like I become completely apathetic and confused. And I'm not sure if I have borderline personality disorder or some dissociative disorder. I don't have a concrete self image of who I am or what I want it can change by the minute to hours to days. I thought I was indecisive but my personality and personsa and who I am can rapidly change inconvenientl .
