Sorry to hear you have social anxiety. It can be really crippling.
If you're willing try going to a therapist and they may be able to help you overcome social anxiety.
Try forcing yourself to go outside around people, when someone says hi try saying hello back.
Share:
Hiding or suppressing anxiety actually produces more anxiety.The most useful step
is to share your experiences with family and friends, or even talk about them online
or someone else that you trust.
Breathe:
Your body is powerful. Learning the warnings signs of when your anxiety flares is
important to help you take action, for some people this could be your tensing up
and your mind is feeling chaotic.
Your body and especially your lungs can help. Breathing exercises can help you control your anxiety.
Having a steady breath has a direct impact on your hearts rate and in turn your thoughts.
Your heart will slow down as you breath does and as your breating and your heart rate slow down your mind
and thoughts will too.
