My #1 tip is practice meditation!!!
Practice makes progress.
The practice of meditation can be a potent antidote and effective tool to manage emotions during early recovery. It can be done in many forms from concentration meditation, to guided meditations, to mindfulness meditation, to moving meditations and more. Find what works for you and stick to it. I have grown so much as a person, and in my recovery since I commited to a regular meditation practice. Best of all, meditation is free, accessible to anyone, and can improve emotion regulation over the long-term.
