Thank you for the response. I think there is the biggest source of negative stress is that I've been tasked with making important technical decisions and building off of them. But I have very little confidence in my decisions since I've never worked with the new tools and frameworks I've chosen. What if it fails? In the end, I made the call so it falls on me. I tried to build consensus with the team and get support from management, but no one I've talked to has much experience with these tools so the best I've gotten is a "it should probably work."
Lol. Yeah, I'm a medical professional, I totally get the "no one can help me with what to do and if I fuck up, it's really bad and all my fault" stress.
Been there, done that, lost sleep over the possible lawsuits.
That type of stress is best managed by truly understanding the competency required for the job and an honest self appraisal of whether or not a reasonable and competent peer would possibly make the same kind and magnitude of mistake that you could possibly make.
Do you feel in over your head because you simply are not qualified for the job, or do you feel in over your head because you just haven't yet learned how to be comfortable with making hard decisions with unclear answers?
What do your direct superiors say? Have you broached your concerns with them? Do you have a full understanding of what the consequences of failure would be? Do you have any idea what your superior's reactions would be if you were to make a reasonable call that turned out poorly?
I worked for an unreasonable employer who viciously scapegoated me every time something went poorly and my mental health was in the fucking toilet from the constant fear and distress. I spent my first week of my honeymoon having panic attacks from being away from the clinic for too long.
My awesome therapist looked at me and flatly said "yeah...mentally healthy people don't feel that way about their jobs." And before the end of that session I had realized that there was no way to maintain mental health in that role.
My next employer was almost unflinchingly supportive no matter what went wrong. She understood that we both would have poor outcomes from reasonable calls, and we would both need to have each other's backs when handling the fallout.
The pressure was still very intense, but it didn't damage my mental health and I learned to respect the risks inherent in the difficult decisions I needed to make, but I was no longer afraid of failure. Failure was just a normal part of my job and something that needed to be managed with clear-headedness.
So what is your situation?
Are you simply underqualified for the tasks assigned to you, or are you excessively afraid of failure? If so, is that fear coming from somewhere internal or is it coming from external expectations, or both?
I am personally now not even remotely afraid of professional failure. I don't take on tasks I'm not reasonably qualified to do, and I expect that poor outcomes are a normal part of competent work. I also don't take on risks with probable negative outcomes that I can't handle. I now see reasonable failure as a critical part of learning. The key is to assess what failure is reasonable.
