Obviously you need more energy. It begins by getting enough sleep, so try to go to bed earlier. Cover all vitamins and minerals, then try other things that can boost your energy safely. Ensure good ventilation, both at home and in the office. Avoid air pollution as it can drain energy quickly. Once you fix your energy, you can then work on finding purpose, but don't quit your day job too easily if you don't want to lose your relationship.
