I do agree with you, and definitely, people need to take responsibility for themselves and their recovery, and be pro-active about it, but then again, I think one of the best things about this forum is that people can just say however they feel. For example, I'm always whinging and moaning about one thing or another in the 'How Are You Feeling' thread, but in real life, anybody who knows me will say I'm not really one to whinge. However, I do it here because it helps me to write things down, regardless of whether or not anyone comments on it. The point is that for many this forum acts as a place where they can get things off their chest. If somebody posts something that you find negative, rather than get annoyed by it, try thinking of something constructive to say back to it that may influence the poster into a more positive mindset? That's surely a more effective way of reacting to it rather than abandoning a forum, which for many, has been a massive help as we all try and recover from S.A together by sharing our true thoughts and feelings in a place where we can't be judged.
I just feel that this forum is a very useful place, whether I agree or disagree with the comments, and I think it would be a shame for you to leave just because you don't like some of the negativity.
