Do you know any online support groups for PTSD people?

As is asked. I’m in China where psychology is literally totally ignored. Actually they started this field only about 10 years ago. Less than five hundred psychology doctor among 1,300,000,000 people are really good enough to give appropriate treats on depression, and they’re busy giving only medication treats cause there’re so many people.
I’m 22, and it’s not until this year did I first saw the word PTSD in Night Shift, and not until a few days ago when this kind guy on Fluther suggest I check if I had it, did I realize I’ve been troubled and exhausted because of it since I was 3.
It was the abuse from my mother. I check this website on helpguide about this disease and about 20 symbols among the 25 listed I’ve been feeling my whole life. Every week, every day.
Due to the situation of psychology and mental care in China, I think it better not to rush to a therapist. I think I’ll try self-care first. I WANT TO FIX THIS DESPERATELY, literally. I do mean it.
And they said I should tell to trust people, challenge the sense of helplessness, etc. “If you can’t find a support group in your area, look for online groups.”
And here I am
