Why am I afraid

Huntyr
So I am 18 years old and go to a local culinary school and yesterday we were doing literally nothing and some of my friends asked if I wanted to cut class early and hang out. My instant reaction was to say no and I did. Now that I look back WHY DID I SAY NO!! I said no because I was afraid. That had never happened to me before. All threw high school I had really bad anxiety and depression so I always shut people out. It wasn't until senior year that I found my passion. And now I'm with people who share my passion and I feel like I can finally be myself and not feel judged. Yet I was still afraid. I don't want to be afraid anymore.
