I hate my parents for giving birth to me
Have your parents done something to hurt you?
They were there for my older sister but they never paid much attention to me. It was like I didn't exist. They ignored what I wanted and I was always put on the back burner.
It's wrong to hate your parents, because they brought you into the world, and have done everything they can to help you.  It might seem like they are favoring your sister, but they are doing their best to give equal effort to both of you.
They didn't do their best. They didn't do everything they could to help with my depression. When I came to them and asked for help with my depression and after how they treated me, they didn't care and said to suck it up.
I'm sorry to hear about how your parents responded to you telling them about your depression. It's important to remember though that parents are human too and will make mistakes sometimes. It's important to try not to hate them and to be able to forgive them for their mistakes.
