Same. The two big stresses as an IC are "I have a difficult problem and I might need to ask for help or admit I can't do it, but there's no deadline closer than the end of the day" and "Production is on fire, which means I get to feel like a hero for a few hours and then do a writeup begging for time to fix our stupid problems." Stressful, but not too scary since there were no other humans involved. When I briefly tried to manage my own team the problem was, "The whole team is staring at me during this boring-ass meeting and it turns out the company's problems are not something I can solve as quick as I thought I could" Letting down customers is stressful, too. When we had big customers quit I took it kinda personally. A lot of hubris involved I guess
