I'm sorry your going through this! I would not worry about the diagnosis and let a mental health professional do that. (I know it's hard not to though. I have issues with that too) yes you should see a mental health professional if they are causing you that much trouble. You can always talk to your guidance counselor at school, teacher you trust, or other adult mentor if you don't feel comfortable talking to your mom and they can aide you with finding help and telling your parents .
