When people hear PTSD, they don't understand how crippling it can be and some people have it worse than others too.
It's important to remember though that this is a new treatment and though it is proving to be working so well and they have not noticed any side effects it's not YET approved to be used in the general population. They are not saying it's a cure for ptsd either, but that those who have tried the treatment have definitely noticed a huge difference and feel hope where there was little hope due to how debilitating ptsd can get.
It's good to share the link with friends who can share it with their treatment providers so it may speed up things so others can benefit from this treatment. Also so that treatment providers become aware of this treatment as well.
