Am I depressed?

I feel not sad but just really empty. I think I look fat and I kind of want to be anorexic to give me an excuse not to eat. I don’t have interest in stuff. I go to bed late late, like at 12:00 on school nights sometimes. I think about how it would feel to cut, and if it would help. I don’t want to die! I get sensory overload a lot. Wow this sounds depressed written down. Can anyone tell me if I’m depressed! I’m a 12 yr old bisexual kiwi girl and I don’t know if I want help. I’m kind of ok the way I am rn, but am I depressed.
