Stay positive because you can not change anything in the past but for sure you can work at your future. Learn from your mistakes and keep your head up
And that's why patience is very important in this. As you are being impatient, this will lead you to overthink. This will result you to panic cause what will come to your mind are those negative side of it. As you have committed a mistake, don't let that mistake brag you down instead let it be a lesson and make it a strength so that as if the same situation as where you have mistaken came again, you already know how to deal with it.
