Lostboyalone,
Others have welcomed you, so I will just comment on the screen name you have chosen. All of us know those feelings of being lost and alone; that comes from the terrible burden of what has happened to you. There is a lot for you to read and talk about here, and I hope you will soon discover that you are not alone. That is a wonderful thing that happens quickly to guys who come here. Quite often a new person thinks that he will never be understood or accepted, and then comes here to find this great crowd where we all know exactly what you are talking about and will never blame you.
On being lost, yes, we have all known that feeling as well. Guys you talk to here will tell you that recovery is one of the most difficult things you will ever do, but you are not lost anymore and you can get your life back. A lot of the support you need you will find here.
On the chat room, guys will sometimes welcome you and ask questions in order to get you started with the group in the room. But if you feel awkward or don't want to talk yet, just say so and things should be okay. Don't feel you have to move faster than what you feel okay with. There are no rules, and the guys here will want you to feel safe and comfortable. Chat is moderated so if anything happens that you feel funny about, just tell a moderator and he will help you.
As you are young, you will get a mod buddy who will look after you and also help you to feel safe here.
Take care,
Larry
