Anyone else get frustated with addon brakeage?

Anyone else feel like when you try and fix a line of code or replace a code or make a slight change, it feels like something breaks then you gotta go rework said code to make it not complain?

I feel like every change in my addon ive made so far, has either worked, conflicted, or had an line value arguement that causes me such annoyance.

Is this what being an addon dev is like? coding headaches and thinking "is this a waste of time?"
