Welcome to the forum @Former-Member.
I know just how hard it is. It took me until I was 40 to talk about how difficult it was for me to talk to people, even just to be around them. It was in an online forum like this. I found out I wasnt the only one and many other people struggled like I did. It was a lot easier to talk to these people (well, type with them) as I didn't need to explain anything, they just understood. Over time, I felt a bit more confident and it becane a little easier, even face to face.
Almost 15 years on I still struggle and find it very difficult in person, but I've gotten a lot better at it... not good, but better.
So I think you're off to a great start by posting here. Its not easy reaching out and sharing like this, especially when its something you haven't really done before. So just keep reaching out, communicating eith people in which ever form you find comfortable and things will start to become easier. It probably wont happen quickly, and there may be days you feel luke you're going backward, but thats normal... just keep trying. There's quite a few people here who understand what its like as well, so you're definitely not alone.
