I am sure Cedars will give you a good reading, and some useful advice on your question.
I myself will only give some responses, seen out from life experiences.
First of all.....We shall all have a dream....and if possible we shall follow it....if not....we will later start to regret...and ask ourself....what if.
Second....if we burn for a thing....and we feel we have the abilities....and even the ideas....then we shall pursue it....it might not always be a success at once....but we will be able to explore....even if we must take some "side work" in order to survive....in the end we know.
Third...or maybe first....do finish school.....you will be surprised how often you will have use for your education...even if we can't se the connection directly.....Education open your mind for thoughts....education broaden your view....which you also will need in storytelling if you want to do it serious.
As for beeing killed....or hurt....then life itself is the greates danger for that.....there is fare more citizen that are killed, on open streets, then police officers.....there is far more injures done in a kitchen...then on the most dangerous workplace.....so live your life to the full...with the normal attention to own security...then you will have a better life.
And as a ending....always have belief in yourself...you must pay for every action you do in life...then be sure it is your decission that are the reason, both for happiness, or eventual downfall.....one is for sure...Life comes never with guarantee...that is why none can tell you what to do
Good luck
