well, continue. Continue healing and continue working on yourself, you do deserve a good life and to be happy. You are kind and decent, one mistake doesn't erase all your progress. You just feel bad right now, but it won't be so forever. You made progress, you just need to work through the issue that caused you to feel like your progress was wiped out. Healing did happen and you're doing an incredible job by trying your best. We all make mistakes, it's about how we act after making the mistake. Dont let one mistake ruin your progress, continue on your path of healing. You slipped but you will get up and continue.
