Hello, I know it may be difficult sometimes to deal with parents like yours. Your parents should not by any means be treating their son like that. That is verbal abuse and you should not have to deal with such things. I would suggest talking to a trusted friend, adult or school counsellor about the issue and maybe they could help. You could also call Kids Help Phone or find a local Child Abuse Centre where you can talk to someone about the issue. Just remember, it's not your fault and you don't deserve to be treated this way.
Hope I helped, PM me if you need anything else, I'm always here to help.
