You could have those feelings for any number of reasons so I won't make any assumptions about the cause of your problem, but maybe hearing out some others and finding a cause and solution you might relate to would help. Personally, I found that I had the "burnout" feeling throughout my career in instances where I didn't see a path between what I was doing and where I wanted to be. So all the work I was doing felt extra draining because the output didn't seem to be helping me make steps towards where I wanted to be. The other times I felt defeated/drained are when I didn't have a clear goal of what I wanted in the future, so any efforts at work seemed pointless. Yes, I was working for a paycheck, but you can do anything for a paycheck, it was important for me that my efforts contributed towards a bigger picture. So in that case, I had to sit down and really find/set a goal. Doing anything without a real goal in mind results in just a mindless/lazy churn that feels pointless.
