What i learnt in my psych class at uni was that a mental illness is caused by biological, psychological and environmental factors (either, or all of the above). Yeah, there are conditions such as schizophrenia, bipolar, ADD etc that are passed down genetically, though it's not always the case 100% of the time.
It's like what comes first, the chicken or the egg. Did the chemical imbalance come first or was it other contributing factors such as environment that then caused the chem imbalance.
The way i view it, if you know someone is going through a depressive cycle/period, slap a watcher on their arse, they need observation. You gotta know what signs and symptoms to look for. Once someone with depression starts having suicidal ideation they'll eventually come to a decision, as a result they may think their death is of little consequence.
To answer your last question Kaz, personally speaking, depression is apart of "myself". When i get mild depressed i am still "myself" though with changed patterns of though, I don't see myself as becoming a different person because it's what i've known to be like for the last 8-9 years, though others may view this differently. My close family and friends know i suffer from it, so they notice the changes and keep a close eye on me and offer me support. And yes, IMO i see suicide as selfish
