These are mostly for managing your baseline anxiety levels:

Valerian capsules help, but get a good brand like Oregon's Wild Havest, valerian tends to pick up lead in the ground. Valerian helps a lot with panic attacks, too.

Make a habit of drinking rooibos tea. After it builds up in your system it counters cortisol (in my experience, very effectively). Mountain Rose Herbs sells quality rooibos.

Cut out caffeine, or try to limit it to green tea. Green tea has L-theanine in it, which helps with anxiety. I'd like to point out that caffeine doesn't leave your system completely for quite a while and reduces your quality of sleep leading to cognitive decline over time.

Eat well, sleep well and go outside more, preferably involving vigorous exercise.

(I have no affiliation with the brands mentioned above but if you're going the herbal route, quality is an important factor and those brands have worked quite well for me)
