Bonjour Marianne,
I started about 1 month ago to pratice SFQG to heal my anxiaty. (Probably not as severe as you though).
I am doing better and better.
The first week, I could barely feel my body : too many worries ("Am I doing it right, should I do this this way or that way, if the master saw me he would say I'am all wrong and reject me, I do not deserve to be healed because I am anxious and can't focus !! It is sekfish I wont use my powers properly...).
So I began thinking : "The master, The unikverse loves me anyway, let go and let them love you" while praticing up until I began to feel love (about a week).
The I went to think : "I am selfich ? I want to know what I really want". So I asked to be healed of what keeps me from knowing what I want. A few days later, I found knew thing I want in my carreer and I am going to tlak to my boss about that tomorow.
It's like I am solving personnal issues a step at the time.
Every time I pratice, I choose a theme I want to release and I keep asking for healing it while I pratice until it feel ok.
Then, something else comes up and I deal with it.
I don't know if I am doing it the proper way but I know it works : Anxiaty is fading awway.
I would suggest to try one aspect to find one part of your anxiaty that you wnat to heal beacause you are sure that if that part was not there you would feel better. Then practice asking for that specific healing.
Hope it helps ?
Take care,
Daniel
