You have so much in those six lines, but can I pick up on just two points that might help you?
Survivors spend years suffocating their feelings, as you say, but those feelings are precisely where our problems lie, and hence where our recovery lies as well. It's essential gradually to allow yourself to feel again. It will be rough at first, since once you really let go everything can just flood out, but hang in there. It DOES get better.
On friendship here, yes, you are right in noting a lot of personal connections on the site. Rather like real life I suppose. There isn't any reason at all why you wouldn't be able to establish the same sort of relationships as you get into things and post and talk to people.
I'm glad you bring up the subject, actually, for the reason that it's something you are concerned about. You are stating your needs, and that's one of the most important things we have to do but often find difficult.
