I honestly wish I wasn't born, is this normal to feel?
You have go to be joking, the world is so nice if you know where to look. Why do you wish you wasn't born?
Bad grades and a boring family
If you really think that way then you should talk to a therapist. Otherwise your mental health may get worse.
You don't understand because you have everything you want
Therapists are there for you to speak to when you have a negative feeling to not be born. They can give your medications or help you cope with sessions of talking to help you feel better again.
