You did nothing wrong, it would definitely be good to talk to your counselor, these kinds of comments are never good to hear especially with what you have been through mental health wise. From what I can tell you are not a selfish person or a brat, your parents however are selfish and emotionally abusive.

In some ways I understand even though I was my mom's first I always played second fiddle to her life and when she finally had a daughter she put everything into her while claiming she was not able to afford the one gift I would ask her for on my birthday.
