"After battling severe panic attacks in my early 20's, I experienced a big transformation, one that changed my life forever. Meditation, breathwork and replacing unhealthy habits with healthier ones were some of the incredible tools that went along with this rebirth. I know now from experience that the biggest challenges we face are often our biggest opportunities for growth. Yes, we can feel alone and overwhelmed when we're in the thick of things, but nothing is permanent, and if we do the work we can come out on the other side stronger than ever. That is something I wish for everyone. … Today, on World Mental Health Day, I want to share some of the tools that helped me overcome my panic attacks, and gave new meaning to my life, in the hopes they might help anyone going through similar challenges. …The smallest changes we do today can have a direct impact on our days, weeks, months and can make the biggest difference in our lives. Just remember always: be kind to yourself." —Gisele Bundchen
