I have been wilding for a few months, no success .

My recent trials failed at the same step. After relaxing, I started counting. At some point, I suddenly cannot feel my body, I belive it is SP. I tried to continue, but I couldn't breath and my heart beat crazily. I felt like dying. Then I breath and my wild failed.

Am I doing something wrong, is this normal? How do I get pass SP and break the dry spell?
