The site itself, as in threads and discussion, not really.
Some people in here, yes, a lot. I've improved a lot, I've had both good and bad experiences. I've enjoyed the good ones and learned from the bad ones.
Right now my anxiety is much, much, much better but I'm still fighting with depression. I still have to learn how to live without worrying to much abou others. Not as in what others think of me but as in what they do to me.
I won't say names (and some have even left) but some people have had a really important presence in my life and my heart in this past year and I will never forget that.
EDIT: it helped me get the motivation to get better, but I was the one who had to work to get better. WE are the ones who have to work for ourselves. This is just for support, just like therapy. They can show us some ways to get better but in the end it's ourselves who have to work.
