I need to visit my GP as my mother is concerned of my health (blue lips, constant fatigue and always cold, etc.). I don't want her to come in the room with me but I'm only 13. What should I do? I think she'd be super suspicious.

If you're wondering, I don't want her to come in as she tends to over exaggerate things. For example, I started eating cleaner over the past few months and she tells everybody that I am now a stick and never eat and count calories etc, which is untrue. I also am getting a blood test and have scars on one of my wrists that I'm afraid she might see if the doctor uses that one.

I'm really scared. Please help me.
