I think my family is abusive but I don't want to believe it.
Why do you think they are abusive?
I have old scars on my body.
You need to let someone know. They can get you help and get them to stop doing this.
I can barely tell the truth sometimes so I am not sure about what happened.
If you think something bad has happened you can share that with someone who knows you and who you trust and see how you can get help.
