Well, as someone with a passion for connecting with others I couldn't be more different, but I didn't come here to rub that in everyone's face. Mainly, I came to talk about online friends. I got into writing about 10 years ago, and by posting on writing sites, I eventually found another writer, who respected my potential but wanted to help me improve.
Since then, he and I have become super close, sharing our writing, offering each other feedback, and even giving each other advice on how to grow as writers. I know his first name, his screen name, and his hobby, and that's about it, but I feel a strong closeness with him that I haven't felt since college, even overshadowing the friendship I have with my roommate, who I've known since 2nd grade. This is because we're both always helping each other out and have a strong mutual trust.
My point is, even online, you can build surprisingly strong friendships. I think trying to grow as a person, by cultivating certain skills you're passionate about can be a great step towards building your confidence to reach out to others.
