I'm not sure what my current T thinks about it. In general, though, she thinks I spend too much time on the internet, and she's right. My former T thought it was helpful when I posted on a BPD board but later she had concerns. Mainly, she said that I get confused when I get responses that I disagree with, and it makes me spin my wheels more than I do already. So she wondered if it was helping me or not.
She was right to the extent that I am probably too much affected by responses I don't want to hear. I think everyone else is an expert rather than making my own decisions. Still, I'd never give up posting on this forum!
