Hello Phoenix, people find posting on a site like this to be embarrassing, to open up and tell them how you are feeling, but it's anonymous, and when you make a comment, then people will reply, but that doesn't mean you have to reply to everyone, you can choose who you want to talk to, something like with your girlfriend.
The trouble with the friends we have is that they aren't sure what they can say to you all the time because it may not help you, so they tend to not be available, this is disappointing, so on a site like you can open up as much as you like and talk with those who have been down this horrible road themselves and offer suggestions as well as support.
It's not necessarily a group, this is a thread you have created and only those who want to reply back to you, will do so, and more importantly, it's people who want to listen to what you want to say, so it's like having a couple of friends who understand and want to support you through this.
Take care.
Geoff.
