I can totally relate to this. Going through something similar. I guess any personal life emotional burnouts can make us see day to day problem solving at computers as too huge a task. Difficult people at work or managers make it worse by questioning you and your work further instead of showing any empathy. In that case if you switch, starting to learn lots of new things becomes challenging as well. I guess thats also a kind of emotional burnout. All the best trying to take care of it with work.
