So basically this is something I excel in because I give zero f***s in most of my life.

I mean even yesterday, I danced like a maniac at a party and didn't care what anyone thought about me.

1. Stop looking around. Don't interpret that person's facial expression as something negative- it might not even be directed at you.
2. Try and accept yourself. Even if you don't fully, try and look at yourself and find the things you like.
3. Surround yourself with people who bring out the best in you. The people who won't judge you.
4. Understand that one embarrassing moment is not the end of the world. Everything will resolve itself one way or another.
5. Remember that everyone around you is just trying to fit in just like you.
6. Let go of your doubts. Dance like no one is watching, sing like its the last song you'll ever sing, dress in clothes that you feel comfy in and laugh like a hyena.
