Is having an abusive family grown up a real lifelong challenge? Is having poor brain chemistry leading you to making decisions you don't "want" to make a real enough challenge? Is crippling anxiety that prevents you from doing anything and not having emotional support to fight it difficult enough?
Who are you to judge what a person's mind is feeling like? You have no way to know someone else's demons. So the bad taste in your mouth is no one else's doing.
