I agree. Speaking as someone that suffers from depression and anxiety, this game is a little tough to play through; as much as I love the characters, my mood has drooped playing the game, and I'm unsure if I can continue doing blind playthroughs - especially since I'm seeing everyone say how almost all the endings, even the "true" ones, are sad.
Life can be gritty, and cruel, but there ARE good things that happen. Happiness may not last a long time, but neither does sadness. Like everyone else has said so far, "happy" endings don't have to be fluffy, and Disney-like. But kind potential could be good.
