I highly recommend that you completely give up caffeine, it reduced my anxiety by about 75-80%

As mentioned in the title. It has done me wonders in terms of anxiety. My heart no longer starts racing, hands no longer sweating, I no longer feel like I'm about to have a panic attack. The best way I can describe how I feel is I feel like I'm on some anti anxiety meds, but I'm not. It will help you with many other anxiety inducing topics as well. Good luck!
