derealization and the overexposure to mental illnesses

over the past couple years ive noticed a odd pattern. mental illness is becoming more and more prevalent and obvious. is this a factor of the internet? has diagnosing gotten better? or have we started to become ill to some external factor (conspiracy). derealization is something that i believe ive had on and off for the last 2 years or so. i dont really know what could be causing it but i feel awful most times.

what is your opinion on this?
