Can I get in trouble?

[Jan]

Shut down your computer, go outside and have a life with real people... hiding in your virtual insanity isn't going to make you cope better with the loss of your dad. It's a very lame excuse and no matter what, you shouldn't assume someone else's identity.
Be yourself and if you can't, go get professional help.

Unless kik messenger's terms and conditions prevent you from posing as someone else, there's not much the police can do, but it doesn't justify your actions.
