I’m diagnosed with generalized anxiety disorder and I’m currently on 15mg buspar per day, it helps take the edge off but lately ( due to more stress at work) my anxiety felt out of control again. 

Replacing my daily coffee(s) with matcha tea has helped me tremendously. Matcha reduces anxiety because of its high content of L-theanine and doesn’t give you the jitters like coffee does. I’ve been doing it for about a week now and I haven’t had one panic attack since. I’m in shock that something so simple has helped so much. Maybe it could help you too!
