I drink and listen to old country. misery loves company.
Surround yourself with happy people. Do the opposite to prevent yourself from hurting or feeling sad. To deal with how you feel; try to talk to friends who help and understand why or how to correct your sad moods when you are happy.
I try to listen to a cathartic song that is somewhat relevant to the sad situation I find myself in- could be sad, could be happy. Depends a lot on the lyrics.
i get out of my house and if thats not possible I watch whose line is anyways episode. Especially season 5 episode 5. If that does make you happy or get you out of your sad mood. NOTHING ever will =D
I listen to instrumental.
