Self loathing is real, but I do sometimes get the impression that people go on and on about how much they hate themselves are really crying for attention. It's hard to say who's just fishing for positive feedback and who's really struggling, though I'd have to say even someone fishing for positive feedback is struggling too. Everyone needs attention now and again, and if they have to resort to telling everyone how awful they are to get it, they probably aren't getting it from people who matter.
