(Question) Should I go to the hospital because I have persistent lack of motivation and fatigue?

There have been times before when I felt a lack of motivation or a sense of lethargy. Usually, during those times, I would feel better after a day or two, or at most 3-4 days, but lately, I have been living a constantly lethargic life with no motivation. Sometimes, I do feel a brief burst of energy for a day or two. I'm a bit worried that this might be the early stage of depression. I'm unsure whether I should just wait for things to get better or go to the hospital to get checked.
