As @Chad_Dupuis advised, getting help from a licensed practitioner is the way to go.
But if there are no licensed acupuncturists in your area you can try to experiment with relevant patent formulas like Xiao Yao Wan variants or Calm Spirit Formulas:
Start with low-end doses of a single formula, keep a daily journal of any changes, and immediately discontinue if you get any adverse symptoms.
Also consider starting a daily Qigong or T’ai Chi practice, which will create deep, long-term healing of your inner being. You’ll get benefits almost immediately, that will deepen as you progress.
“Systematic Desensitization” is an especially effective series of techniques to eliminate anxiety that you can learn from mental health professional, assuming they’re trained in them.
