I think I might have ptsd

Wen I was twelve I was forced to drink a can of alcohol,


(My dad also has severe ADHD) 


He argued everyday with my mother,


I was abused mentally and slightly physically,


Everything is ok now but I get flashbacks and hear noises wen I hear men shouting in anger,


I left out some bits of my story,


I'm also only a 13 year old boy so I quite don't understand ptsd fully,


If anyone has any advice to help me treat it please tell me
