A pastor flat out said I was going to hell. He even preached it from the pulpit. His daughter attempted suicide a few times, nearly suceeded once and then one last attempt and now she's dead. Welp.
I'm not saying you are doing this, but there are people who can take one case like this and use it to represent anyone who preaches the gospel and includes hell in his or her preaching.
Certain people in depression are quite able to feed on negative thoughts and ignore what would help them; plus they can filter so they are pointing only at what uncompassionate people do, instead of finding who can really help them get cured by God. Also, depression can make us clever enough to criticize the ones who tell us what would help us; they, for example, may tell us how we need to be corrected, but we can spit that out and say their criticism is uncompassionate.
I, for example, have had a very into-myself personality. People would say so, and I would consider them to be rejecting me. And then I kept breaking down, more and more until I became suicidal. I could very cleverly throw out people who were telling me the truth, and feed on what I wanted to think.
Otherwise it's usually, "It's cause you're an athiest"
If you have pre-conclusions as an atheist, this can effect how you filter things, can't it?
or "Have you really TRIED praying?"
It "depends" on how I pray. If I'm nasty and making myself the judge of God . . . this "might" help me to keep filtering out what could help me. It's not exactly being humble. If I hold on to what has helped to feed me into depression, instead being "swift to hear" (James 1:19) for what I need to find out, how am I going to get what is better?
"I'm sorry I don't know what you're going through but you're in my prayers" (I appreciate the last one)
My opinion is we humans all have had the same basic problem; so yes we can understand each other from our own experience. But depression has its way of filtering this out and making us our own dictators of who can understand us and help us and who can't; and then, when people and methods under our dictatorship fail, this feeds the depression more.
I recommend listening to what someone says, and be open to how it could help . . . even if the person is not perfectly compassionate in how he or she said it > I have found, later, often enough, how ones have told me what I needed, but my filter kept it out while I was still being into myself.
You say you can be "sad" in depression, I think you mean; I'm more of a "mad" type in depression . . . aggressive so that suicide would be aggressive, in my case, I think. Others, I think, are trying to escape pain.
