Well you certainly have got yourself into a right pickle, but more importantly you may have time to rectify it before you totally mess up your life for good. Please do see this as a major wake up call.
Firstly, you can't be made homeless under the age of 16, the council will have to house you or do a short term foster care. It is illegal to put anyone under 16 on the streets.(ie a Landlord), thus you are protected in that way.
Secondly, stop messing up your life, do what your parents tell you, and begin to act like the adult you are trying to be.This means taking responsibility for yourself and the things you do. Realise what you do in the next year will have everlasting effects on your life,so you have two choices:
1.Carry on the way you are and end up in jail for petty crimes, leading to more criminal activity, drugs etc. Never achieving anything, being surrounded by people you can't trust, always looking over your shoulder for the Police. Most importantly NOT LEAVING A LEGACY TO INSPIRE OTHERS.
or
2.Get your head in gear, stop playing around, start living, be the real person to inspire others, into achieving their dreams too. Stop the crime, change your friends to those who don't get you into trouble, do your schoolwork, do the revision, and SET YOUR STANDARDS HIGHER. Set your goal to get really good grades next year, and then college, uni, or an apprenticeship. Be the person you would want your kids to be, and have the life you would want to look back on when your old and be proud of.
You later schools years are VITAL in getting a good job, you have to score well in your exams,or do retakes. It literally means the difference in getting a decent job, thus housing, cars, holidays, partner etc. Education is one of the only ways out of poverty, or to become independent. Life is soooo much easier with a good education behind you.
Don't mess up your life before it has even begun.I want to see you achieving great things, so what are you on here for, get moving to a better life.
