Is it normal to rock back and forth

I've done this all my life I sit Indian style on the floor( cris cross apple sauce) on the floor listening to music and rock back and forth. I relaxs me I honestly enter places in my head I didn't know exist similar to a writers like I live completele worlds out in my head and it relaxs me. I got married 5 years ago and stopped cold turkey he doesn't know I have done it or ever would but I feel like I'm falling apart nor do mykuds 4 and 3 know about it. I'm just a stressed out mom. I'm stressed and overwhelmed all the time but I don't want my husband and kids to think I'm insane. I've lived this my whole life my brother was dosagnos AdHD feel like this was way to deal with adhd and without it I've developed severed social anxiety disorder and I don't know how to get happy and relaxed again. I don't know if this is I adahd lllsymptom because of the co start motion.
