It is highly likely that you're experiencing burnout because of the sheer volume of things on your plate. Perhaps you are working multiple jobs, shouldering family responsibilities, dealing with conflict, engaging in multiple projects, and trying to maintain an active social life. All these activities take energy and mental capacity. What's more, co-ordinating them takes even more out of you. That extra amount is like the delivery fee on top of your Uber Eats order—a relatively small amount, but one that adds up over time. The main takeaway is that there are costs to doing a lot, and there is an additional toll that comes with managing everything. 

In addition to the actual workload, burnout is also influenced by how you think about your work. Yes, this is getting even more meta. One common negative thinking pattern among those who experience burnout is imposter syndrome. Imposter syndrome is a belief that one's success is not due to personal effort or skills, but to external factors such as luck or low standards of employers/others who assess your work. This belief creates a fear of being discovered. Any moment now someone will realise your inadequacy and make it public. To avoid or at least delay the inevitable, you try to do everything perfectly and never ask for help. This fear and perfectionism contributes to emotional exhaustion and eventual burnout.

The problem is therefore twofold: 1) the actual things that you're doing, and 2) what you think about the things that you're doing. Managing burnout requires making changes in both areas.

If you are currently experiencing burnout, you might be tempted to focus on what got you here. But let's face it, you can't do anything about the series of stressful circumstances that led you here. That's definitely spilt milk not worth crying over, especially if your burnout symptoms already include some tears. Instead, focus your attention on what you can do to cope with your current state, recover from it, and reduce the likelihood of a recurrence.

Let's start with the first and most important step: acceptance without judgement. Given the sheer amount of things you've been doing, it makes sense that you are burned out. It is not a personal failing, it is not a moral judgement, and it is most certainly not something that you should beat yourself up over. Just like you would not judge a car for running out of gas, don't judge yourself for running out of energy.
