Has anyone here ever had experience with chronic ptsd?

I went to see my doctor today to get a referral and the doctor had wrote on the clinical notes that I have chronic ptsd. I haven't been officially diagnosed with this by a psychologist, but I have long suspected I did have some ptsd, due to being raped, abused, assaulted, bullied, seeing the aftermath of when I was a kid and my dad almost died, to losing my mum unexpectedly.

Can a family doctor write you have chronic ptsd without you being formally diagnosed by a psychiatrics or psychologist?

For anyone who has suffered from chronic ptsd what did you do to help you?
