Thank youTwo things, diet, and investigate your issues through whatever methods you can use. Diet will help with the PTSD, anxiety etc. on the physical level, and sorting out any issues will give you deep inner peace.
Official medical practice loves to belittle these kind of experiences, totally dismiss them if it can, but there is some movement towards actually using psychedlics as treatment, I don't know if it will ever be officially endorsed though. For the medical industry, there's no money to be made out of healthy people, therefore there is no money in long term cures for anything.
For now, increase your protein intake significantly, but not dairy, dairy is dodgy for a lot more reasons and for far more people than is officially recognised. Beef is very slow to digest, so chicken, fish, and ironically, whey protein, are good.
For therapy, anything will do, even just talking on here to people that have had similar experiences will help reduce your stress. I have ADHD, so I am absolute rubbish at proper meditation, but as a teenager, I discovered that I have very good visualisation abilities with seems to amount to much the same thing, it certainly involves a different level of consciousness. I'm very into dream interpretation as, done properly, it provides a window on the psyche, requires no drugs or equipment, and is effective for everyone regardless of beliefs.
Oh, and sleep! Get as much as you can, and if you have problems with sleep, diet can help with that too. So can meditation or visualisation etc. It all ties in together in spirals, e.g. your body needs protein to repair damage and replace used up neurotransmitters, so we need more when we're hurt, exercise vigorously or are emotionally stressed. Not getting enough makes us even more stressed and depressed, Once you have broken the downward trend and recovered, you naturally don't need so much any more.
Your words make sense
