This seems like an effective way to train your brain to do or not do what it is doing. And there are no medications involved here. Could this really work? No medications, simply training your brain to feel desired emotions and not feel the undesirable ones. Here are encouraging results shown in this article: “In results from a more recent study, Dr. Young says that after two sessions of neurofeedback, depression scores dropped 50%. In the control group, they dropped 10%. These results are not yet published, but were presented at the Society of Biological Psychiatry annual meeting in 2015.”
Sounds promising. I would give it a try.

Excerpt from article: 

In neurofeedback, patients lie in a functional magnetic resonance imaging scanner. In general, they are told to conjure memories or look at pictures while their brains are scanned. The activity of certain brain regions related to subjects’ illnesses is analyzed via computer. Patients see visual representations of their brain activity almost in real time—often presented in the form of a thermometer or colored bar.Based on what their brains are doing, subjects are told to enhance or suppress that activity. Patients “need to train their brain like they train their muscles when they want to be fit,” says Anna Zilverstand, a postdoctoral researcher at the Icahn School of Medicine at Mount Sinai in New York and lead author of a 2015 study using neurofeedback to treat women with a phobia of spiders.
