A Fiona
Fionas are the people who will love you to death, then tell you you're a 'disaster' for not texting them back.
My Fiona said I was her favorite person, then called me a 'disaster' for not texting her back.
My Fiona told me I was 'amazing' then yelled at me for not being there for her.
My Fiona cried over me, then screamed at me for eating her chips.
