Hello @goodloan. I'm sorry to hear about your girlfriend's problems. PTSD is not something to take lightly, but I'm glad she has been able to get some help.
I see you're asking people if they have experience with it. I'd suggest joining the Health & Recovery community, which is for topics related to health, recovery, treatment and so on. Maybe you can connect with people who have gone through it and get some help/opinion.
There's also another community, called Mental Health, which you may be interested in, but can't be sure which one would fit better as your post is too short, I'm judging only by the tags you used here. Maybe if you'd write a bit more about the case, someone would be able to guide you.
Thank you. I will look into those communities over the weekend
