adult son with PTSD

[Inaquandary]

My son is 28 and suffered sexual abuse at the age of 4, at the hands of his cousin who was 13 at the time. I didn’t find out about it until my son was 13. By then I was a single parent. I didn’t know what to do.

Now, because I didn’t do the right thing then apparently, I am being blamed for my son - who still lives at home with me, doesn’t work or support the household - having PTSD is my fault. I took him to a private psychiatrist, he has had lots of therapy but still can’t function, his words not mine.

I have no idea what to do next. His GP seems uninterested - I think he has had all the help the NhS can give him over the years and private is just too expensive at £350 an hour.

I feel guilt, helpless and anger. On top of all that my mother who has PD lives with us. In UK.
