You can't expect to have energy if you don't exert it. Anything more than slow walking is excessive. The body wasn't meant to run long distances or do unnatural exercises like bicycling that weren't around when the species was evolving. Too much peak performance depletes you and siphons off energy the body could be using for healing purposes. Be nice to yourself, slow down, relax, sleep more, do nothing.
Modern life is too stressful.
Quit your job, learn to meditate. In general, tune in, turn on, drop out, and trust things to come to you. If you love enough, the universe will support you. If it won't, it's proof you're selfish and thinking about yourself too much. Insecticides and herbicides are poisoning you.
