I need someone I know to tell me not to do this.
Why do you need someone else to tell you not to?
I'm following orders from someone who tricked me.
If you are in an uncomfortable situation and are looking for an excuse not to do something, you shouldn't do it. You don't need someone else to tell you not to do something that you are already uncomfortable doing. Rather than rely on others, you should learn to stand up for yourself and tell someone no.
Eh I'll tell the person that I don't think it's okay.
That sounds like a good idea. It's always good to stand up for yourself if someone tries to get you to do something you don't believe in.
