My younger sister at your age used to be in your current situation, depressed, hardly talk to anybody (even to my mom), doesn't go to school, locked herself up in the room.

We doesn't know what went wrong. In the end, we sent her to stay with our grandma at my hometown. From there onward, things changed. She started to go to school & seem enjoy the life there. She scored beautifully in her SPM, went for Japanese lesson & is now pursuing her degree at Osaka University.

The above scenario is just for sharing purpose. Come to the end, it's all depend on what you want & how you want it to be.
