As a child，I was generally happy，singing and dancing to my favorite songs，smiling and laughing with my friends and family．But as far back as second grade，I noticed a"darkness"about me．I didn't enjoy participating in many things．

In middle school things in my life began to get even worse．I began withdrawing from everything I once enjoyed．I was always tired．Everything was horrible．Finally，midway through eighth grade，I was told I had a chemical imbalance，diagnosed （诊断） with clinical depression，and had to take medicine．It took months for me to feel the effects of the medicine．

When I began to feel happy again is when I realized that I had to take the responsibility for getting better myself，rather than relying on medicine．Aristotle said，"To live happily is an inward power of the soul，"and I believe that this quote describes what I had to do to achieve happiness．Happiness is a journey．Everyone seems to need different things to be happy．

"The essentials （要素） to happiness are something to love，something to do，and something to hope for，"a quote from William Blake sums up what I believe people need to realize to be truly happy in life．People need love； I feel they need their family and their friends more than anything else in the world．People need work to do，something to make them feel they are making a difference in the world．People need to know that more good is to come in the future，so they continue to live for"now"instead of constantly worrying about the bad that could come．Love and hope are happiness．
