I am new to this program and I am nervous about it. I am in week 2 and m anxiety seems to be worse. I have a knot in my stomach most of the time.
How long before this goes away?

Who knows?

Welcome to the site! As for your question, it's different for everyone. Stop focusing on the time it will take. Just work on the program, you will feel better and better as you do the program. You'll be fine. Communicate with others and post and respond to others, you'll start to feel better about your progress when you realize you are not worse than everyone else. That usually makes us feel better.

3D,
This is very common. Lucinda speaks of this. Becoming aware of what causes our anxiety, and dealing with those feelings can in the beginning make it worse. However, it gets better. I promise. I started the program in August...way house bound due to agoraphobia and now am in a new job, have moved, and am approaching every day with strength and courage. The anxiety still takes hold of me at times but, I am much more aware and know that I can handle it. Be gentle with yourself....minute by minute,,,Soon,,,you too will see how powerful this program can be.
