Dear Tony,
Most people with psychiatric histories have some fairly serious emotional wounds. I certainly do.
When you are physically hurt -- think of a scratch that draws blood but does not require stiches or too much attention -- there are certain specific steps you can take. You can clean the wound, you can put a bandage on it, you can take care of that area so that it does not become hurt again. But you can't heal it. For more serious wounds that is even more true. You -- or medical staff -- can make it more comfortable and easier to heal, but the wound needs to heal itself on its own schedule.
Emotional wounds are the same way. We can't heal our wounds and neither can doctors or relatives. They need to heal themselves on their own. But we can create conditions which makes them easier to heal.
I can't tell you those conditions. They are specific to you. But they probably involve doing things which make you feel safer and more comfortable. Possibly coming up with things you can do to prevent a similar trauma from occurring again. Listen closely to what will help you feel better. If you look for a way to calm down, you will eventually find it.
