As everyone else has said, just get in the water as much as possible. With or without your board. One day when you're at that point when you usually would have passed on a wave, you're gonna have to just say "F&#@ it!" and go. You'll probably eat sh it. But you'll realize what you were scared of before, really isn't so bad. And as far as being new to the scene and not knowing anyone, stick with the attitude you've got and keep showing your face. Show consistent effort and keep your humility (as you seem to be doing now), people will be much quicker to bro up with you.
