I have social anxiety. Can you recommend anything to help?

I am sorry to hear you suffer with social anxiety. This must be very difficult for you.

Have you considered trying NLP, Life Coaching or Hypnotherapy to help tackle your social anxiety? 

Practitioners of these therapies are trained to help you see and overcome challenges in new and different ways. The links below will help you find a local therapist:

Support groups (online or face to face) can also provide a means of sharing experiences and discussing tools that may help.

We also offer a range of flower essences which can help rebalance emotions when faced with stressful situations. 

You could try Confidence Essence to address problems with low confidence from both the past and the present.

I hope you find a path to follow that helps you to overcome the anxiety you currently face.
