How can I regain interest in things again?

I used to be really interested in Paleontology, Zoology, Marine Biology, Oceanography, Meteorology, Geography, Astronomy, the Revolutionary War, and the American Civil War. I also would listen to classic rock for long periods of time as well. But over the past couple of years I feel as if I've lost interest in everything, and just can't read about those subjects I mentioned anymore. When I do watch a documentary about them I do not pay any attention to it and when I try to read about them I don't understand them. I feel like I just have no interest in those subjects anymore. Also I'm at home 24/7 and I rarely get to go anywhere at all, so I hardly ever get out. I want to be interest in those subjects again like I used to be. What do I do?

Loneliness spurred my anhedonia, but health is a holistic concept. There are multiple factors... physical (are you sleeping, eating, exercising properly, etc?)... sense of purpose... social relationships... spirituality... it's all tied together. If one area in your life is lacking, then it will mess up others.
