Hello, it seems that your social anxiety is related to your speech and articulation difficulties. It is understandable that it must be difficult for you in such a scenario.
My strong suggestion to you is to seek consultation with a psychiatrist and speech therapist concurrently. The combined approach from both is likely to help you fight the circular vicious cycle between your speech problems and social anxiety.
Do not lose heart and seek an early consultation to help your condition.
Hope this helps you, best of luck for your health and future.
