There is no signs of any form of mental illness going back through either side of my family. Plus I think the jury is still out within the medical industry as to why some of us get the disorder and others don’t.
My personal opinion is that if you perhaps are susceptible to it, and a trigger in your life sets it’s off, then unfortunately that’s all it takes to bring the disorder to the forefront.
Similar to an alcoholic, if you have an addictive personality and continue to drink heavily then our actions and lifestyle factors must be taken into consideration.
I will be completely honest here and say in my early 20’s, before mental illness reared it’s ugly head, I used to smoke marijuana. I honestly believe that was to my detriment and played havoc with my mental health. Apparently marijuana has a very negative effect on women more so than men. I know people out there will say otherwise, but my poor choices back then I am sure did not help in causing me my mental health issues, particularly with several bouts of psychosis which I have had.
Heavy weekend drinking with friends also wouldn’t have helped my situation, binge drinking basically but you can’t change your past…. but move positively forward with the future.

Hereditary for sure. My father was an alcoholic who had depression (undiagnosed). He committed suicide. Then there’s me, with bipolar and a former alcohol abuser. Then there’s my son who became depressed at age 10 and wanted to kill himself. He’s fine now after 2 years of treatment. So there’s 3 generations of mental illness
