I think I may have Bipolar Disorder or BPD?

[Audrey]

Hi. For the past two or three years, I have had symptoms of both Bipolar disorder and Borderline Personality disorder. I am 14. Sometimes, my highs and lows cycles within moments like BPD. But, most of the time, I have feeling of mania or depression that last for a few weeks respectively. Could I have both? However, my main question is this:
How can I tell my parents? I went to the doctor for depression a few years back, which resulted in a hospital visit and à few therapy sessions. They could not have acted more inconvenienced. So I am scared to tell them this.

Also, if I'm not too depressed to do anything or manic as hell, I feel... numb.

Also, a few other things REALLY scare me... like, when I'm depressed, I would kill myself if I had the energy to do it. And I would do drugs/alcohol if I didn't fear getinng caught...

Any help would be appreciated.
