Saying things like this is really really dangerous in my opinion, because in addition to being totally false it can discourage someone struggling with depression / anxiety / whatever from seeking treatment because they don't want to feel "numb." I'm sure I can speak for not just myself but many others here and say that without antidepressants I'd probably be dead, and the only part of life they've eliminated are the lowest valleys of depression. At one point I considered not taking them because I believed in this same misconception (I was afraid to lose my creativity), but I'm very glad now I did not give in to that fear.
Please do not spread misinformation about potentially life-saving medication.
