I can relate, too.
I only really have one friend and I met her on this forum. We've been close for over a year now but she lives thousands of miles away so we've never met in person. I want to go over and see her more than anything but I'm absolutely terrified! She of course has SA too so we would both be feeling the same way, which is maybe a small comfort, but on the other hand conversation might be very hard for us both (I, for one, have no social skills).
I think an ideal situation would be to arrange something where conversation isn't the primary focus. A movie is a good idea, but personally, for me, something quiet and less crowded would be even better. I haven't actually come up with many ideas... only that it would be a lot easier if there was some sort of activity/thing to focus on 'doing' other than just making conversation.
In my situation though it may not matter any more because I think she's lost interest in me recently, which is why I joined back up on here; somewhere to vent my grief maybe.
