Just got rejected from my dream school

So yesterday I found out I got rejected from dream school. I worked extremely hard to get in. Good grades volunteer work I even did an summer immersion program at their school. I feel like the interview was where I messed up just because I was so nervous. But I don’t know what to do now. It feels like everything has just stopped and I’m going to be stuck feeling like this

I figured I’d post on here because I feel embarrassed to go to anyone about this but I need to get some stuff off my chest
