Recently, I have been having a lot of anxiety about my health. First, my heart was beating fast and I thought I was going to have a heart attack or I had a heart tumor. Then, I got concerned about my breathing and thought I had a lung tumor. Lastly, I thought I was forgetting things and that I had a brain tumor. Can you see that pattern? Try as I might to stay positive, my anxiety keeps coming back. So, I am looking for some breathing techniques to help myself calm down, relax and enjoy my life.
