I think PC in general is a great place.

I think a healthy forum is one where someone can say, "hey, I am struggling," and then other people jump in to offer guidance, support, etc.. It is also nice that we have PM's where people can get more "one-on-one" attention if they need someone to talk to (as I know it can be difficult to talk one on one in a thread sometimes).

There will be trolls and stuff of course -- because how can you avoid them? -- but most people are genuine and sincere, and they want to help. The fact people are willing to spend time with you to help you feel better is what makes a forum great.
