Aloha! There is a huge gap of misunderstanding and denial regarding the way for humans to find wholeness and balance. The mainstream medical systems fall far short in most cases. All scars, psychological, emotional and physical - can heal, provided the right process is allowed and the right understandings are gained.
I have been using methods of deep healing for many years that are highly effective and mostly unknown, however, they are not simple to explain. The bottom line though is that unconditional acceptance of real emotions and allowance of safe expression of them as sound is a necessary missing step in human health at this point and the most healing thing anyone can do. Total self acceptance is extremely powerful and when combined with the right internal intentions can trigger deep healing - however, there needs to be a holistic approach that addresses all levels too simultaneously.
Usually, there are stigmas, self denying beliefs, trauma walls and misunderstandings that prevent the right flow of energy into and through all of our parts - this fragmentation needs to end in order for us to come into balance. Careful attention to nutrition, self care and ideally some yoga/breathwork can all help. Being willing to listen to the ailing parts of yourself is important and something that the mechanistic, profit driven medicine systems have limited to zero understanding of.
I can go on and on, but will let you respond if you prefer before I do! ;)
Wishing you well!
