Most pdocs specialize in writing prescriptions for medication rather than therapy.
A therapist who is trained in psychotherapy would be who you would want to find to begin therapy.
An internist might be caring, but would not be trained in providing therapy. I'm sure that the interest and caring that the internist is showing feels good and it is so nice to have someone care.
But for therapy, I hope you will consider finding a qualified psychotherapist to provide you with helpful healing therapy.
