I do too. It took me a few years but I learned breathing techniques to breathe in counting to 8 through the nose, hold for four and then let it out like a lion's breathe. AHHHHH. a few times...close my eyes and know that I am here, grounded and alive. And it's okay. Live in the present moment. Turn off the monkeys in your brain that are bringing the past and the future into the now. The past is gone, the future is not here yet. Breathe in and out....you are loved.
