Yeah, people let us down, don't they?

I guess it happens to everyone, but it doesn't make it hurt any less.
You said you try not to put your hope in people. I understand that ... one thing about depression is that it can cause you to start withdrawing from people, for fear of exactly that, I guess ... getting hurt. (Believe me, I understand!) But in reality, it doesn't help to do that. We need people. We just need to find the right balance between putting our hope in
God alone, while still allowing Him to show His love to us
through other people. It seems like maybe that's what you're doing by coming here.
I don't have any great advice, I'm afraid. Just wanted to let you know I'm listening and I'm praying for you.
