It is possible to have ptsd or complex ptsd from emotional abuse yes, it is not often recognised in descriptions of causes though. I have ptsd from emotional/mental abuse and neglect, but when looking at information on ptsd it is rare that it will be listed, usually its sexual abuse and rape. C-ptsd is a little different, it is abused by prolonged emotional abuse and neglect. This doesnt mean you definitely have either though. Ptsd is diagnosed based on the amount of time since the traumatic incident occurred, and what symptoms you possess, for example nightmares, flashbacks, loss of interest in life and things you used to enjoy, avoiding things that remind you of the traumatic incident and anxiety. I would suggest looking into the symptoms of ptsd and complex sure to see how many symptoms you possess, and if it makes a lightbulb go off for you, see someone who specialises in it. The longer you leave ptsd untreated the more a part of you it becomes.
