Our emotional and mental and spiritual problems can manifest themselves as physical problems. The worst thing you can do is to try to go through this alone!!! Telling your mom would be a good idea. Do some research on Hakomi Therapy. Search for the website. It is a body centered therapy that helps to get "stuff" out of your body. Do it while you are young. It will help your adult life be so much better and can help to prevent disease and dysfunction. You may also want to look into massage therapy and acupuncture as a way to deal with the back pain. Look for solutions that do not stress your liver out. Your body is smarter than your brain will ever be. It is trying to tell you something. Listen to it. I wish you the best as you begin your journey!
