I am really bad at making up my mind when it comes to the main six :/
My Current
Pinkie Pie
Rainbow Dash
Twilight Sparkle
Applejack
Rarity
Fluttershy
But I love them all really!
Don't have a favourite episode (yet) but favourite song would have to be: "Find the Music in you!" Closely followed by "A true true friend!" "Smile Smile Smile!" "This day Aria" and "Flim Flam Brothers Song!" Oh and Generosity... You know what I love em all!
I also love to read.... Like a lot :) I love to write and my favourite kind of mlp episodes are the deep and sometimes emotional ones :)
Eh I know that feeling Find things you love, forget about the absolute rubbish life can chuck at you sometimes and focus on the this that make you happy The day isn't over yet, don't worry until it's over! There is ALWAYS time to turn things around! Hope things turn round man
