No one is saying simply “don’t stress”. Recognizing when stress is centered around something outside your influence can be a step toward dealing with it. That may not work for some, but it does for others - as I said, different strokes. Making a broad generalization about what is and isn’t good advice is reductive and only shuts down advice that may help OP

Dismissing advice that doesn’t work for you personally isn’t helpful - different strokes and all. I’ve dealt with anxiety and have found that rationalizing emotional responses to events outside my control normally works well for me. Ultimately, there’s no one-size solution, so people need to try different approaches to find what works for them. A variety of perspectives is always best

Ironically, these are the sorts of questions you should be asking a therapist. More general advice is to only allow yourself to stress about things in your control. There’s a lot of shittiness in the world, and stressing over it is poison to your mental well-being. Focus on what you can change and let go of anything beyond that. It helps me to try giving people the benefit of the doubt, e.g. imagine a scenario where your therapist ghosting you is justifiable - maybe a close family member of theirs was in an accident - and choose to believe that. While it may not always be correct, this is a much better way to live for your part.

Running fewer commands as root is more significant risk reduction than having an extra user. I won’t be replying further since I’m simply repeating what others have already said. If you sincerely don’t understand, I suggest doing additional research on your own.

You seem to be looking at the issue in black and white. Any reduction in root access is beneficial. Using sudo with password cache lasting an hour is still preferable to signing in as root. As many people have said, it’s about minimizing attack surface

None of us can tell you the right approach for your specific system and use-case. People are simply pointing out that what you stated you’re doing is insecure and not recommended

Are you asking why it’s more secure to surface a few commands without password rather than all of them…?
