Living with bipolar disorder: Maarten opens up

Bipolar disorder is a serious mental illness that can cause unusual shifts in mood. They can range from extreme highs (mania) to extreme lows (depression).
Maarten Hemmen is just one person who wanted to speak on the issue. He is determined to change the stigma of this mental illness.
There are four types of bipolar disorder. The symptoms can go from mild to severe, sometimes even with hypomanic episodes and depressive episodes.
More than 350 million people in the world suffer from this mental illness. They struggle to lead a normal life. What makes it harder is that societies do not speak openly about the issue.
Maarten runs a blog on his condition and his experience with it. He knows it is a challenge, but he is determined to change the view about people with bipolar disorder. This is his story.
