You use sarcasm unironically quite excessively.
Where's this depression you speak of anyway? Signs of depression are behaviourally: not going anymore (avoiding the sun), withdrawal from friends/close acquaintances, not engaging in usual activities, etc. Sentimentally: guilt, irritable, miserable, sad. And the thoughts of a depressed patient are sampled as: "I'm a failure" "It's my fault" "I'm better off dead". Any absence of these elements pertains intellectual dishonesty and spread of false gospel. Though, she was actively helping/extremely shinobi-like post that point, and demonstrated positivity that shinobi could succeed, as well as they and herself were being underestimated, in the ultimate battle. If they're present, the symptoms I speak, then Sakura can be established as at least, semi depressed, given her valour after the supposed depressing moment.
