Why do i have no energy and motivation for months now.. im only 27?

Many possibilities.: I would suggest you start off with seeing your primary care physician. The symptoms you describe are nonspecific and there are many conditions that could be causing them. Your primary care doctor should be able to help you sort this out.

Fix the cause: Lack of energy can come from a variety of situations. Dehydration (not drinking at least 5 cups of water a day), lack of sleep/poor sleep, skipping meals, stress, sleep apnea/snoring, chronic sinus problems, caffeine withdrawal, chronic illness (such as anemia) or allergies can cause low energy. See your doctor.
