I think this is an interesting topic that reveals more about ourselves than the platform, as you said, it revealed that you were a control freak ;).
I feel your pain, i felt very similarly- but ultimately i think its been for the best, I've learned to be as honest and open as I can in a moment, and give myself a break when "looking back"
We're only all doing the best we can at any given moment with what we have <3 I try not to be so hard on myself
