According to [url=http://allaboutmedicalsci ence.blogspot.com/]medical science[/url] If you have depression, you may feel hopeless and sad or stop feeling pleasure from almost everything you do. You may feel down in the dumps, tearful, or discouraged. You may also be irritable or anxious or have low energy levels. The symptoms of depression are often subtle at first. It can be hard to recognize that symptoms may be connected and that you might have depression.
