How do I persuade my parents to give me medicine for anxiety and depression?

Name: Aarti Date of Birth: 15 May 1998 Place of Birth: Jaipur Time: 04:20 PM. Hello, I've had anxiety and depression for more than a year, and I feel I'm at a stage where I need professional help. I've done natural treatments, counseling, and changes in my lifestyle but my symptoms are still impacting my schoolwork and relationships. The catch is, my parents do not believe in mental health drugs. They believe I can simply "stay positive" or "pray more." I wish to tell them that medication is not a sign of weakness but an aid to enable me to cope. How do I make them understand this without being rude? What's the best way to make them believe that I need such assistance?
