Hi, I will share something that has helped me with anxiety.
It is real. Last year we lost my younger sister at 53 to cancer. My 77 yo mother is constantly saying I am all she has left. Two weeks ago I learned I have a CAC of 1,208. We are waiting for more tests. We are not telling mom. I obviously want very much to outlive her. I am 5 years older than her father when he died of "hardening of the arteries" on his 52nd birthday.
I think the first thing to do is externalize and not identify with a condition. Anxiety is a condition. It is not an identity. Sense of self comes from where we choose. It only comes from what happens to us or from physical conditions if we allow it.
Feel the feelings. They are real. However, if we see them as a condition to be addressed, rather than identify with them as who we are, it is allows step forward. We are not our illnesses.
