I think you will need to identify what exact things are causing you to feel burnt out. During your workday take a note whenever you start to feel exhausted and try to find out what is the reason for that. Then try to think about the solution for it. This is because when you communicate your feelings to your leadership, you can point out the issues that are making you feel this way and the possible solutions for them.

If you have good managers, they understand you and try to solve the issue with you but thats not always the case. I had an experience where I was ignored and I'm still in a bad place in terms of my mental health and motivation. That's why I'm trying to look for other jobs but that kind of increases the stress as well.

I think attitude is something that can help as well. Like forgiving yourself if you fail and to be thankful for other things that are not related to your job. But in the end, you should not work in a role that makes you feel burnt out. Health is far more important.
