Your body wants that too. The body will point out what isn't working, and simultaneously what you can work towards. It tells what not to do by examining the pain metaphorically, and it tells you what to do, by looking to the healthy functioning of the injured area. Use the body as your teacher and discover a new world of freedom. The brain and emotions can be another source of information, another mirror, and another teacher.
Many schools of psychology encourage people to get into their feelings.
Just feel it and release it. The implication seems to be that freedom is obtained merely by witnessing the thoughts. It definitely helps to witness. You've got to be able to be honest with yourself and introspective to navigate your brain. The emotions hold as much information for us as our physical aches and pains.
