Hello there! Anxiety can be evaded. There is medication available in Homoeopathy which can cure anxiety altogether. But for the start, I suggest deep breathing and alternate nostril breathing (naadi shodhan) for starters. Try another technique , before you speak with the person or people who make you nervous, take a deep breath, and exhale forcefully with the sound of "Hah" or "Hum" , if you are in a public place and get nervous then breath the Hah or Hum into your hanky. Doing this 3-5 times helps you gain the courage to speak with who ever makes you nervous. You can also look up "Singhnaad aasan" on the net and practice that,it brings out the lion in you. If you need Reiki or homoeo medication, mail me at jhageetanjali21@gmail@com . I do distant Reiki Healing sessions at a very reasonable cost. Hope breathing exercise works for you. All the best.
