If any of those don't work then something gloomy to match the mood would be great.
Main images/gif; See the 3 gifs and image I linked above!
Text; Kristy, are you doing okay?
Subtext; Can you stay strong? Can you go on? Subtext 2; Don't waste your whole life trying to get back what was taken away. (*NOTE* this is the second subtext and I want it to be away/apart from the main text and subtext if possible. If this is not possible then please leave it out.)
Font; Whatever you think looks good.
Text colour(s); You choose.
Straight edges or something different?; You choose.
Any extra info; This is a sad siggy. Not meant to be happy so not too bright or cheery please. xD Other than that - go nuts!
