Feeling Sad- I find myself the most depressed when the people closest around me (especially girls that I have feelings for) withdraw from me and don't act the way I want them to. When people don't act the way you want them to, it's usually not because of something that YOU are doing. Rather, it is the other persons' problems and insecurities manifesting themselves in this way. You are most likely not doing anything wrong. Continue to smile and be a loving person. Soon enough, you'll feel better. Change is a big part of life but I find that time heals allllll wounds. So give it time.
