Otoharo!
No one else can say, but I recommend that you not take other reiki classes. Reiki is helping you deal with stuff you need to deal with., Trust reiki. Be reiki as much as you can, for instance, keep a hand on yourself all the time. Your belly, or your chest. Reiki I is the one to deal with what you have.
About how to deal with stuff. I had so much stuff it took me from 1957 up to about 2002 to deal with it. I literally cried days on end. walking down the street, I would be silently weeping. However, crying can be a smoke screen to keep one from dealing directly with what is the matter. I had therapy five years.
Reiki's effect is the upchuck of all this. It is up to you to look at it, own it, even say it outloud. Then feel yourself release it. You have no further need for it. Tell your guide what you are doing so you have someone private to share with. You will get thoughts back.
Release the fear as soon as you are able. Talk about it here unless you want to keep it private. Ego controls all of us through fear.
I have to chuckle when I say this. Xaris asked me what is the fear. I did not have fear. Several times at different intervals she asked this, then she asked What is the terror. Boy! The top of my head popped off! so i can feel for you.
