Hi chazzap,
This country and British society have been so ruined over the last few years, usually by the EU and PC Brigades, that so many youngsters are now in the same hopeless situation. Even New Labour admitted recently this generation will be a 'lost generation' with no hope of their own home, job or future.
I don't think much of your mother I'm afraid. Why did she allow her new boyfriend to push you and your sister out of your home? A decent parent puts their children before themselves, yet New Labour have now taught adults to put themselves before their own kids - encouraging mothers back to work for example and telling them their children can fit around that with child care.
I would ignore the rubbish about the fortune teller. Your mother believing that is another sign of her inadequency, weakness and general lack of intelligence and character. You should consign the predictions to the same place as your step-father and accept the real world.
Do you know the American Indian legend of the bluebird? Everyone has a bluebird perched on their shoulder signifying happiness. If you leave the bird alone it will stay on your shoulder - but if you reach out to grab it, then it flies away. The more you reach the further the bluebird flies until you stop trying the grab it and it settles back on your shoulder.
If you don't give up hope then happiness will find you in the most unexpected way. No one can say or predict how. You might fall off your bike say, and the person who picks you up is the girl you spend the rest of your life with. Ten seconds later and she would have been gone. Keep trying for jobs and you will find one that suits you and makes you happy. Forget the football too. Millions try to be stars and they all fail. You'll be no different.
Good luck chazzap. Don't give up. When you are really down then things will only get better. Remember the bluebird.
