Why did I choose these disorders?

I chose to do Depression and Bipolar Disorder because they relate to me in real life. One of my best friends in the entire world has both Depression and Bipolar Disorder. For many years she has been seeing a psychiatrist. She has also been on medication to treat it. This friend of mine has had extreme highs and extreme lows. She was diagnosed with Depression at young age.About four or five years ago she was also diagnosed with Bipolar Disorder. The doctors were able to diagnose this, through blood tests. Her mother also has Bipolar Disorder and that is why they decided to test my friend. I have never witnessed a major mood swing from my friend, because she has always been on medication for her Bipolar Disorder. Although I have never witnessed a mood swing, I have witnessed her extreme highs and extreme lows.

So one may ask why I chose to research both Depression and Bipolar Disorder; well, my answer would be that it is near and dear to my heart.
