Turn on good music. and slowly start to clean up. Don't think about anything bad! only about the positive! Just start to put the things in place. Then retracted gradually! Good luck to you my friend! success!
It happens all depression - it passes quickly. when you have close friends!
I always put on music when I clean and end up feeling really happy. Dancing and singing. It is just getting to it that is hard and I already started and have gotten a lot done!! :D I am a cleaning machine!
Also, my depression does not pass quickly. It probably isn't clinical depression if it does. It is just being sad. ;)
