Dude this is deep, Alot of people don't understand people like me and you who have PTSD, mine is all linked to my birth and is a built in thing for me so i have nightmares and flash backs. it is horrible.
i am so happy that you are feeling well with out having to take medication, that is brilliant news.
I am on medication for mine otherwise I would not sleep, or I would drink my self to sleep as this is the only way for me. I am still lucky to get about 4 hours a night.
I have been sectioned 3 times in my life, and i have tried to end it too on a number of times.
i am too in a better place in my life and feeling happy, a few of them things you have put into your list I have had to put into practise my self.
I have started eating more healthy, I do more, and put a lot into my home life. and we have moved a way from a neighbourhood that was so bad that we have seen riots out side our house.
this move has done me good, and my kids are happy too.
good luck for the future and I hope you stay well.
