Relaxing and taking a break can be extremely hard in everyday life.  There is school to worry about, family, chores, and so much more.  They are all distractions. Your emotional health and well-being must come first.  A good way to slow down the activity in your brain, is to cross your wrists, lace your fingers together, and fold your arms towards your chest.  Then, cross your legs as well.  While you do this, breathe. Another good thing to do is to take yourself away from the chaos of the world. Turn off your computer, your phone, and the lights. Turn on classical, or some sort of easy listening, music and, again, breathe. When the world feels like it is slipping away, or you are having a panic attack, try to ground yourself.  Good grounding methods include counting, or naming physical objects around you. Do this until your heart rate calms down.
