How much was the wristband btw? I say go for it! I'm the same way, where if I'm with a friend or agreeing to meet someone at a bar beforehand, I'm super talkative, but the idea of approaching others just scares me to death sometimes. The more I drink, the more I open up tho

Definitely take it slow! I think it helps having a friend who pushes you to talk to others. But like the other person said, the only way it'll ever get easier is by talking to more people and learning how to return the vibe and emotion that they give you!
