what is the genesis of mental illness?

[Dinko]

there has been a lot of talk about mental illness in chat lately, and I was wondering as to the root cause of it.

I was also thinking that you know how Diabetes comes as type 1 or type 2 (the first one you care born with, and the second is acquired during a lifetime, usually because of lifestyle choices), that perhaps there may be mental illness that is born hereditary, and then the rest of it is a 'condition' that is the result of a pattern of life. (like being extremely traumatised or what not).

just a thought; and no disrespect to anyone for bringing this up.

thanks

genesis is lack on nutrients and doing drugs like cyan
