Gus,
Only you can know in your heart what is best for you. I believe that this is a good place for me to be, that these are good people for me to befriend. I have been fooled, but I have been fooled and betrayed in the real world, too. If I react as I have always done, by boarding myself up inside the fortress in my head, who will I hurt like that? Not the betrayer. Who could I help like that? Not myself.
Lurk if you have to. Just take time off if you have to. I have done both of those things at times in the last year when I felt I needed them. I have seen others take time away, too, and come back. There are a lot of good people here, extremely brave people with kind hearts. If you really must be away, please remember that they are here, and will be here when/if you return. They have always been here for me.
Joe
