4. Amy Winehouse
Died at a young age of 27, the talented jazz and soul singer, Amy Winehouse, desperately struggled with bipolar disorder in her last years. Due to her bouts of depression, she started to smoke and drink heavily, and her consumption of drugs increased, which led her firstly towards the declination of her singing career and later on, in her health. Unfortunately, Amy was so deeply indulged in these habits that she did not want to quit smoking, drinking, or drugs. In 2011, Amy was found dead in her house due to over-intoxication.
