This feeling can be overcome on your own, you just need to make a little effort. How to do it?
When I am sad, I try to quickly get rid of this feeling. Even light physical activity can improve my mood and state of mind. So, if I feel sad, I can do some exercises at home, or go to the gym. Jogging helps too!
Also, I can do something pleasant for myself :) For example, I can watch an interesting movie, especially some kind of funny comedy, or an exciting adventure movie. I can listen to my favorite music or eat or drink something tasty… Cleaning also helps a lot! Half an hour cleaning the apartment can work wonders! Everywhere it becomes clean and my mood improves!
What about you? How do you deal with sad feelings?
