Maybe this will help.
I will not ride in car when the driver is impaired.
I will not lend money unless I don't care if I get the money back.
I will not spend time with people I don't want to spend time with.
I will not do something just because someone is trying to make me feel guilty.
I will not pay attention to other people's advice unless I think it might be worthwhile.
I will not let other people make my choices for me.
I will not say yes when I mean no.
I will not let someone talk me into doing something that I am not willing to do.
I don't need to tell these to anyone, they are for me. Kind of a mental checklist to help me focus on me and to keep me safe and happy.
Your friend,
