Dilemma

I know I am suppose to be adding a blog about my Christmas holidays, but I have a dilemma. (The Christmas one has been started, but is not as important right now).

What to do? At what point does a person sit back and say it is only a job and I am a person with feelings and can be greatly affected by the actions of others. This has been my issue for ever, I am always willing to do what others want me to do so that I don't make or cause any ruffles. I figured that this experience would hopefully help me deal with this and help me become stronger in doing things that I want to do. I do think that this is happening. But a wrench has been thrown in and a decision has to be made that makes me choose between the teacher part of me and the me part of me. I have to decide which one is the most important. I know the answer to that, but really it isn't that easy.
We all know that the job I am in has not been a cake walk. The children at this school have some major issues, and I have had many worrisome moments. But Friday tipped the iceberg. It just goes to show that a person can never get to comfortable in a position like this. I thought things were going really well, minus the few hiccups I was confident in the relationship I had built with each student. But, being punched in the face deliberately, causing a fat lip and bruising in and around my mouth, put me right back to square one.
So here are the dilemmas, what to do:
1. Go back to work and insist the boy be removed from my class
2. Press charges on the boy (this is the second teacher he has assaulted), in attempt to teach him that it is not alright to do this and that his actions will result in consequences. (of course this is not what the school would want me to do)
3. Leave it, and find a mindless job for the next 6 months. So that I can have fun for the last part of my journey, take a break from teaching and really fulfill part of why I am here. To travel.
4. Go home

I am not sure how I am going to be at work on Weds when this boy comes back into my class. How do you interact with someone who you thought you had a relationship with? What do I do when I ask him to do something and he refuses?

I am soooooooo lost and alone. Magic answer fairy please shine down on me!
