It's a small price to pay leading up to your final decision.
It might seem out of the way and an annoyance, but leaving behind why you did it and all of that stuff helps people move on and understand (hopefully). Unanswered questions would drive me insane, personally but.. That's why I'm writing a note. I don't mind taking the medication before the poison. I am glad to make amends and all of that.
However, I completely understand your frustrations. I have them as well. It feels like too much and it's stressful.
I think you will be just fine in the end, and the decision(s) you make will be the right ones. Have faith in yourself. You've got this and you know you better than anyone else. x
