I agree with Enderman, Niko. One thing that helped me was powerlifting. Lifting hevey weights gave a way to release a lot of energy, and I really loved doing it. I listhen to some Sabaton band music, heavy metal songs about historical battles and wars. "Staying busy" as many say or "just snap out of it" or "just be happy" just DONT work when your brain is rewired during depression. Aside from staying busy which is just ignoring the problem and avoiding it, analyze it or do something you just love. In my case that was Listening to Sabaton, weight lifting, and gaming here and there.
Get better Brother!
