My Anxiety and Chronic depression meds not covered by Classic Priority Option

It is the time to change my medical aid option with Discovery Health. So I would like to downscale as I have no dependents and it is costly to be on the Classic Comprehensive for only one person. I compare the other options and see that the Classic Priority looks like it will cover what I need. However before selecting it I ask one question - Are the chronic medications that I am on for depression and anxiety (Xanor and Cymgen) covered under the Classic Priority? The answer comes back - NO! To get my medication I HAVE TO be on the Classic Comprehensive or Executive which are expensive and unnecessary for me. I'm not happy that I cannot downscale because of this. It has taken years to find the right combination of medication to assist me with the conditions. Discovery Health - help!
