Find some hobbies, do sports when you can, visit interesting/intriguing places, do activities you never had a chance to do before. Find a way to relax, e.g. sauna, deep sleep chambers etc. It's also possible you have some long-term nutritional deficiency leading to your brain literally shutting down some circuits making you apathetic. Try to take a NAD+ booster like Niagen (300mg/day) which is required for energy production and you might want to try 2000mg B1 Hcl and 1000mg B2/day, the first one required for each energetic reaction but depleted by long-term stress and the second one for producing FAD+ (energy production in the brain, similar to NAD+; don't expose yourself to strong sunlight though). You can also try to do some mechanical job requiring little to no thinking like resupplying stock at a supermarket or building homes etc.
