Connecting on a community like this (with at least the intent) of having actual human responses is a good first step. For the sorts of questions about what to do in life keep exploring why you've had bad human interactions and see how you could lower the chance of that happening. For the coding try accepting that very likely you'll make mistakes or do things in a non optimal way for the first pass. Think of writing code like writing a rough draft don't worry about big o etc. Focus on building an understanding and mentally model rather than producing an output (read: source code). AI gives you output and brain chooses lazy way to reach the goal.

Think of non AI code production like a woodworker that can read a piece of wood knows where the knots and the unexpected grain direction c changes are and uses that understanding to make something. Maybe what they set out to build wasn’t actually feasible. Compare to an ai it’s more like a factory it will make cuts right on knots etc. All is focus on output with the inputs at any cost.
