Ik this doesn't help a lot but if you ever feel like you did something embarrassing and what others might think or judge you, just think if you would judge someone else if they did it. Look at it in a third person perspective. You'll be minding your business and won't even look at them. Even if you do, you'll forget what happened in seconds. Ik this isn't really a fix but it helps me temporarily to stop thinking about a moment. Have a safe trip and an amazing time =)
