I would like advice on leadership and stress management.

I'm a tech lead, most of the team I work with have less than a year of experience. The business is quite demanding, my direct manager supervisor doesn't support me very well, and I am very much not interested in changing jobs at the moment. What I would like is tips from anyone who has been here, what works what doesn't.

The specific scenario I am in is this: I feel like everyone around me gets scared they'll make a mistake, and freezes up, and they start focusing on looking good instead of working hard. Every time I show leadership, and confidence get the team moving, some random business person, client or manager steps in, and effectively kicks us right back into the frozen state of affairs. It's driving me nuts. I've resorted to just getting my own work done, and become fairly passive aggressive. Has anyone else run into this?

I appreciate you taking the time to assist me here.
