I want to try to improve my mild depression on my own before seeing a doctor. so, what are some reasons to be happy/grateful to be alive?

Be happy because: depression is treatable (: ! There are many things you can do for depression. Don't isolate. Spend time w people. Use your support system. Get out. Don’t stagnate at home. Work to get 8 hours or > of sleep per night & eat healthfully. Daily aerobic physical activity is a big +. Recommend the “Feeling Good Book" by Dr. David Burns. Don't just read it - DO IT!

Read this: "Happiness is a serious problem" by Prager. It will give you some ways that we all get in our own way to be happy. Also, psychotherapy will help you. Take care

Pay attention to: all the things you have as opposed to what is missing in your life. Also what are you hoping to accomplish in life, what do you enjoy doing? Make plans to include more of what you love. Exercise to help improve your mood as well. At 17 many great things can happen, college will be better than high school and doors will open to new opportunities.

Many: Good health, family, friends, having a job, religion, .....

Mild Depression: You could try regulating yourself as much as possible including, sleeping and eating on time, getting regular exercise, and looking at your life more realistically. That is being sure to have a more balanced outlook on life including positive and not so positive aspects. If your depression worsens or persists, I would strongly suggest seeking medical or psychological care.
