How do you determine the correct mental health professional to speak to...?

I would recomend you to see a clinical psychologist , they have a full medical doctorate & a doctorate in psychology. Many work in family practice clinics & can be seen on a sliding scale fee. If you don't have a good connection after the first 3 or 4 sessions find another till you get one you're comfortable with. Privacy is always guaranteed per patient confidentiality as with any doctor lawyer ect.
