Having excessive doubt, suspicion and violent behavior indicate presence of some severe psychiatric illeness like delusional disorder
. In such cases counseling only, do not help.
Several time excessive alcohol use may lead to similar symptoms, so stop alcohol use (if present).
But, do not worry as effective treatment available and seek psychiatrist
help as soon as possible.
I hope this information has been both informative and helpful for you.
Wish you Good Health.
