You agreed that your parents are very responsible; that means they've done what they should do. right? If your answer is yes, the question lies on other areas as following:
First thinking:
1. why we are born; 2. whether life comes with suffering and/or happiness; 3. any approaches that may solve and/or minimize your present suffering
Second thinking:
1. Many new born babies/children are left/given up by their parents. How do they get to live alone well in society for their rest of their lives?
2. Many unables keep their living like normal people. Why do they do that?
3. Why all of us praise the virture of courages.
I believe that 1. we have no say in the issue of baby born but 2. we have right to choose how to live whether with courage or not.
In fact, life is not easy not only to you but to all. I'm one of them suffering as well as in happiness. So much happiness ahead, don't give up right now, don't be silly.
