Am I the only one?

I don't know why, but I am completely alone. Even tho I want to have friends, I am scared to make them, I am even scared to comment on vidoes or even play multiplayer games. It wasn't always like this, but expecially now I feel like I am unable to meet someone new, to actually have fun in life. I want to have at least one person similar to me, who I can talk to, share hobbies and thoughts. I don't know why I am so scared, but at the same time I crave friendships and just human closeness
