My personality is gone! I'm like an empty shell!! How can I get it back?!?

Awww :( I feel like crying for you. I actually used to feel like that a couple of years ago, so I know exactly how you feel. But then I finally just took a drama camp for the hell of it and ended up loving acting. I was in my school play and made a bunch new friends and have drama cles every week. You just need to find out what you like to do. It may still be making people laugh. You could be a comedian. But if it's not that, don't worry. You'll figure it out :)
