That vulnerability is not sufficient in itself to lead to mental health problems and this is where a second crucial variable comes in: An invalidating environment which can range from indifferently treating the individual through to overtly punishing them.
This is what I wanted to say but thanks for giving me the professional terms Steve2. The invalidating environment of the JW religion is so damaging to people vulnerable to illnesses like depression. Whatever you do it's never enough. If you're a woman you're a second-class person to start with. If you're a married woman and you don't have children you're nobody, even if you're getting 100 hours a month pioneering, still nobody!
The low self esteem is endemic in that religion and if you have a bilogical vulnerability to depression as Steve says you're in real danger of being ill for years as I was. Five years of clinical depression without medication because thirty-five years ago pscychiatrists were the spawn of the devil and medication was a no-no. I defy anyone who says the WTS never said that, I was there! Since leaving I only had one short bout of depression for five months when my parents died and I did take medication.
Building self esteem by gradually achieving more things in life while removing toxic people or groups who drag you down is the key to mental health in my opinion.
Good health to you too Tallon.
