Damn, some of those wounds do not heal up all nice and tidy. Shit happens, really nasty ass shit happens. When one engages in battle and nasty ass shit happens it imprints on us.
Just get over it. No, not the nasty ass shit but the fact it got imprinted on your pshycic. Believe me they are two different facts. You can live with what happened but you cannot live with it stuck in wrong places in your living being.
Search and capture. Do not try for destroy. But capture that bad stuff and put it someplace manageable. Some danged place where you have the keys and not it. Lock it up but visit it and interrogate daily. Learn it, be it, defeat it. Stick tried and true with your training. Understand it better than it understands you. Be the master and not the servant.
When things go south and it is just you out there and it. Tie your foot to a hold first and then engage. The hold will help you come back, and keep you grounded.
As for me I like my big brothers and Christ for my hold. Pick it as you would a member of your unit and never leave it behind, it may be your sanity.
I really do not know much but I do know that if we act like it is bigger and badder than what we have already concquerd it will defeat us.
For me, several times a week I fight it hard wake up sweaty but victorious. I hope the same for you.
