Lack : Lack of energy, lethargy, and "muscle heaviness" are fairly common complaints. In some cases these problems can be caused by neuromuscular diseases, such as myopathy, myositis, or myasthenia gravis. It is far more common for these conditions to simply reflect fatigue, a common and nonspecific condition that is closely associated with depression. A visit to a doctor for an examination, consideration of lab tests, and consideration of additional testing should get to the bottom of it.

Impossible to say: There are hundreds of conditions that can cause these symptoms, and nobody can tell you what it is without taking a comprehensive history, doing a complete physical examination and obtaining routine laboratory tests. They can range from psychiatric problems (stress, anxiety, depression) to physical (thyroid trouble, heart disease, vitamin deficiencies). See your pcp for an evaluation.
