Hi, is it possible for me to see a psychologist using my medical aid? if not, how much does it cost?

Depends: This depends where you have coverage. Every medical aid program is different. One of the best places to start is by calling your insurer (usually a number on your card) and asking which providers you are covered to see. You could also look into a sliding-scale payment program which will use your income and financial situation to determine how much you owe. Good for you for seeking care1
