But for some people they're a necessary evil though! Whilst it can definatly help I don't believe meditation and spiritual healing can cure everything. Not all meds are intended to 'cure' you but, like you said, they help people manage and cope with whatever symptoms they have. Hopefully to the extent where they can live a normal life one day without being reliant on it. Surely that's a good thing?
Also I think they are more psychologically addictive than physical, ie the worry about what 'may' happen if you come off the meds can be a lot worse than what the reality would be
