Attitudes are improving but I still find people saying things like depression means you don't trust God or you do not have enough faith. Anxiety is responded to by the quote "do not worry" or "Be anxious for nothing". Depression means unforgiveness and that is a huge bugaboo in Christianity.
The church has no problem with healing from physical illnesses but seems to stumble over mental illness. Cancer is a disease but MH is not has been the impression I have received.
Usually I get told to forgive, that God will,provide, to fake it until you make it, etc. Such advice is well intentioned but not always helpful, especially when my mental health is affected by problems in my church. I lost the ability to worship when our church had a major scandal involving the worship pastor and the senior pastors and leaders. For someone who was in junior choir in the 1950s and on choirs and worship teams until a few years ago, the loss has saddened and puzzled me.
