Has Dani self-harmed? *NOT FANFICTION*

This isn't me trying to expose Dani, neither am I trying to say that this really happened. I am just showing you the research I did and why I think Dani may have previously had an issue with self harm (maybe 2-3 years ago).
Some people may get offended for many reasons. I do speak a little about stereotypes, which can always be an easy way to get hate, so if anything offends you, please just nicely say in the comment how you would like me to re-word it so that I do not offend anyone else.
If you have further evidence or you have an opinion, then please tell me in the comments, because I would love to hear what you have to say.
Thank you for reading this, and remember that I am not trying to expose Dani in a mean way. :) <3
