I fucking hate this world

Hello, I'm 15 years old. I'm very depressed and I don't want to live anymore. I don't know why I'm living. I want to die and disappear but I will be leaving everything behind me, so I won't do that. I live in Syria, the country is broken, infrastructure I damaged, I don't have electricity most of the time. My cousin had a mental breakdown because of this situation. My uncle has cancer and needs medical attention but I can't. I'm doing everything by myself, I don't have any money or any people standing behind me. I want to kill myself, I want to die, I don't want to live anymore but I will be leaving my family behind me. I'm dependent on my family and I don't have enough money to do anything so I'm living in this situation.
