Dear friend, I can imagine the impact of your parents conflicts on you all. That's painful to be in that situation. I would like to tell you that issues pertaining to family, relationship / interpersonal are dealt by counselors and psychotherapists. To be precise, family therapists or couple therapists. If the counselor or therapist finds them to be having any psychiatric (Medically related) issues, then you will be directed to the medical expert (Psychiatrist). Try to find someone online. I know people in Bangalore.
