Does Prozac cause mental illness? In a word, no. It's just that we're more cognizant of mental suffering. There's less shame in saying I have a problem. So a lot of people who would have been suffering alone are getting help. Even if they are ill in response to stressful or oppressive issues in their lives, the medication and the treatment often allows people to deal with it. To find ways to do things. I don't think it helps our liberation to have people suffering needlessly. I do wish there was more support for therapy- drugs are cheaper but therapy keeps the drugs going, if you know what I mean?
