Were you able to have a read of the document? Hopefully you found it helpful.
The ones in the document that I've used personally are aromatherapy, bibliotherapy, chamomile, exercise, lavender, smartphone apps, meditation, yoga, breathing training and relaxation training. A lot of the supplements interact with the medications that I'm on so I can speak for those. Therapy has probably been the biggest help in coping with anxiety.
Is therapy something that you've tried, or looked into before?
