Things I wish people would have told me:
"I can see right now that you don't seem to care about anything in life and I get why you don't see the importance in the things you are doing right now. The fact of the matter is, that even though you are still young, the decisions you make right now WILL effect you later on. You need to look at what you want for yourself and your life and start coming up with ways that you can acquire this as quickly as possible, because the truth is you are not going to be happy until you have the ability to be self sufficient.
If you want the freedom to do what you know is right and good for you with out constantly meeting resistance, then you need to focus on the fact that what you are doing right now is only putting more attention on you. The consequences of your actions are going to result in people trying to control you more, and you will end up having a miserable life.
You need to figure out what you want and need and start working toward it. Thats the only long term solution. All these things that you are creating for yourself and having to deal with, will only slow you down and make you even more unhappy. So quit acting like a child and start taking responsibility for your actions. Then people will get off your back and you wont feel the need to be destructive, which I know you know, only hurts yourself.
I am saying this because I want to see you happy. If you ever need to talk about anything or just want to do something together I am here for you."
