"what doesn't kill us makes us stronger" is only sometimes true and only in an indirect way. What kills us ends our lives and that is always true. Please don't share tht platitude until you think about it. Idont think we shouldtalk about death with people who are suicidal unless we are sure of what we are saying.

Iwould say that sometimes we feel weak because we can't overcome, and we don't need to tell ourselves we should feel "stronger"
