People tend to look for excuses when they feel guilty
I guess it's a normal thing when we feel guilty, we try to find some holes that we can reason out for that mistake we've made.
so first step is to understand that it is ok to make mistakes, that you are still a human being capable of improvement and adaptation.
Exactly. There's no problem if we make mistakes as that happens for sometimes but it won't be normal anymore if we keep making mistakes. But other than that, when we make mistakes, it's also fine to admit it and then just do our best to correct it.
You are not bad because you are gambling too much, you are bad if you decide to do nothing about it. Forgive yourself, move on, change and improve.
Just be the better version of yourself. Sometimes when we can't forgive ourselves, we're staying to that part that we can't do better because we keep on dwelling in the past and that makes us stuck there. I agree that someone who's struggling to quit just need to admit first that you made a mistake, you're addicted to gambling and then try to do something to move on and make use of your time for some other things.
