You don't need a reason to be depressed! Do you always have a reason why you're happy? Why you're sad? Always? No, not always. Not 100% of the time. Depression is the same way, but while it's not hard to cheer someone up who's feeling sad, depression is harder. It's a difficult thing to deal with. You might feel absolutely terrible, and that's okay. Just know that you're really awesome and wonderful, and anyone who thinks otherwise is wrong.
