Everyone is right in saying you didn't ask to be born, but you are fortunate to have family who cares for you and wish to help. Many aren't given that lot in life. Maybe your father could provide some support to lessen the burdens if you're able to communicate your needs to him.
It seems a lot of people hinge their happiness and success in life on having children and giving them a better life than they had themselves. They put all their hopes into their progeny, and they will perceive it as their own failing if that child goes on to ctb.
While that is admirable in many ways, it's also naive. Children have no responsibility to glorify their parents. They are themselves, not trophy objects, and should be respected as such. Your life is yours alone, and you should objectively decide what you want for yourself.
People who aren't fulfilled in life should think twice before trying to fill the hole by creating more life. They're risking the same unfulfillment for their children for the compensation of having them. The problem is not with themselves, but the environment they exist in, and adding more life to that environment is unlikely to be of benefit.
