my jitter and fearfulness mind

How do people with anxiety live on a daily basis. How can we do certain things when we feel we are judged by the world, how can we survive from the monsters inside our mind, survive the pain we feel deep down inside.
What is holding us back? That heavy weight is holding us back. How does it feel? A constant war with your mind, like you are drowning with your own thoughts and can't get back to the shore because the water is weighing you down to much and everything goes dark.
