Let's first think about what might cause it:
Burnout is a more and more frequent condition in the IT-sphere and is usually caused by working in a toxic work culture which includes:
- not enjoying the colleagues double-faced behavior, or what they do with their money :)
- colleagues who might be trying to get you out of their career path
- experiencing a non-supportive mixed joking / passive-aggressive behavior from supervisors, without being able to respond
- not enjoying the technologies working with such as outdated software, frameworks or languages
- trying to keep up with the pace by learning, and at the same time thinking if you don't know in details about the latest updates, you won't fit inside the team and will be fired
- trying to schedule your rest/work time, by being flooded at an unexpected time with task tickets (time-restricted)
- not having the opportunity to express your view on certain subjects, or when expressing them they are left without a response
- thinking that the whole IT sphere is getting more and more filled with people, who can as well as pick potatoes if the job is well payed
All those can quickly build up and you may start to have repetitive negative thoughts about doing the work and at the same time trying to be cheerful around the colleagues - a form of cognitive dissonance.
The following are my remedies:
You'll need to learn to quickly how to balance between your focused and default brain network:
Have at least 1 hour of walks in fresh air.
Here is some immediate basic exercise, you can do without postponing :)
Do sports, running combined with positively reinforced repetitions of I am ok, I am healthy... fill in some empowering words that work for you...
Work on a standing desk in order to reinforce your focused network, and having breaks as much as you would like. Remember your job and that of an HR is not of the same difficulty :) If, on a budget, you can do standing desk by yourself using some books or cardboard boxes.
Optional: extensively use high-quality headphones
About performing tasks: write the task, in the form of a mini and detailed plan on how to do the task and then just relax and have fun. When it is time to choose to do a particular task, just open the plan and do it, without having to think or improvise ways on what is the proper way to do the task or which task to choose.
Lastly - simply quit your job.
