Is it normal that i rock back and forth?
Basically, the other day I was sitting on my bed, doing homework, and I thought I was completely fine, and all of a sudden, I noticed my hand going back and forth, and I looked in the mirror, and my body was rocking back and forth. Is it normal?? My friend told me she does the same thing, but she's always more stressed out than I am.. Is this a kind of sickness or disorder??
