I need help

I'm from Taiwan. Sometimes I feel like I'm very strange, I don't know how to describe it. When I'm normal, I'm perfectly normal, but when I'm not, I seem very odd to others. Sometimes I feel extremely frustrated, even when nothing has happened, whether I'm walking down the street or at home.

I feel completely drained. At first, I thought it was just because I was unhappy, but later I gradually realized that there was something wrong with my body. My family cares about me, but strangers don't. They might find it funny, like they're watching a joke, but that's not how I want to be, and it's not something I can choose. When I have an attack, I like to be alone. I don't know what to do. I've tried seeing doctors, taking medication, trying to regulate my mind and body, exercising, and doing other things. I've tried my best, but there's still no improvement. I really need help. If I could, I want to be like a normal person. I'm 17.
