How do you handle burnout as a senior security engineer?

Context: my manager is pushing me hard to take on staff responsibilities, which I have been pushing back on for the last 12 months. I am not interested in handling political aspects that come with the staff role. This has caused severe burnout and is making me hate the work and my manager. I have started looking for roles outside, but wondering if this community has any tips.
