What is the opposite of an attention whore?

I sincerely wish that people would stop catching on to me almost everytime I don't appear for two weeks. I have a legit reason to be disappearing and it's not like I'm going to disappear and never resurface ever again.

This is exactly the reason why I 'ran' away three years ago.

I think I may have what I label it as 'You-are-too-concerned-about-me-please-go-away syndrome' and I need a break.

I am Mia, Princess of Genovia. 

(People really need to know when to fuck off)

It's amusing how people feel like nobody shows them any concern and here I am being irritated from too much concern shown to me. I need a guide book called 'How to handle concern from people for dummies'

The wall will always be my sincerest friend in times of need. #perksofbeingawallperson

P/S: I need the answer to my post title.
