Good Morninig Silver,
I am so sorry that things are so tough for you. You did not share what your illness is so I will answer without that information, OK?
Psychotherapy is the most promising method of treatment for Paranoid Personality Disorder.
People afflicted with this disorder have deep foundational problems that necessitate intense therapy. A confident therapist-client relationship offers the most benefit to someone with the disorder.
People with paranoid personality disorder rarely initiate treatment and often terminate it prematurely. Likewise, building therapist-client trust requires great care and is complicated to maintain even after a confidence level has been founded.
Can trauma cause your problems, I cannot answer that with a yes or no. In somecases it could be possible depending on the trauma.
Bless you and atay with us.
