@fjieopwfjqer - please tell your husband that depression in young people is certainly not a product of the 'snowflake generation'. I am 52, and I was depressed, and having suicidal thoughts at age 14. The difference is that now we are far more aware of mental health issues than people we're back then.
Looking back it is clear that I was clinically depressed as a teenager, but it was not diagnosed. I suspect that there are plenty of people of my generation who suffers alone and in silence.
Oh, and just in case you are thinking that my story is proof that you can just pull yourself up by the bootstraps, without drugs or therapy, and that is a demonstration of how tough former generations were, compared to today's young people, please think again. Yes, I struggled through and survived, but my life has been blighted and limited by my illness - and I am sure that, if I had had better treatment earlier, I would have had a much happier, more fulfilled life, and might not be still suffering from moderate to severe depression.
You and your husband both seem to have a very intolerant and unkind attitudes towards depression, and I am willing to bet that this is negatively affecting your daughter's mental health. I know how difficult it is to live with depression when those around you support you and care for you - I can on,y imagine how hard it must be to suffer from an illness that your parents think is nonsense, and a symptom of you being from a spoilt snowflake generation.
