Life is all about choices.... OK, now that being said I want you to concider whether or not "getting along with family" is something you can work on. I know...from experience...that living on your own is STOOPID crazy expensive. So are horses!
Can you burry the hatchet with your family and pitch in more and complain less to show your family...like it or not (you'll have to eat the dirt on this one) that you are a team player and your are trying to mature and be responcible and maybe, just maybe they (parents) will be more likely to help out??? I did this when I thought I knew everything and moved out 2 days after graduation. I had to eat some serious crow and crawl back home until I could gather the money to stand on my own 2 feet. My parents were happy to see me lose my attitude ( I still think I was right
) and work for something substancial. I just let the dumb stuff at home not matter and kept plowing forward.
2 jobs and a car that was made the same year I was born!
It sucked living at home and I had to abide by the house rules..but I really found out that it was no different than working for someone...you have to obey rules and work too. *shrugs* Good Luck and I hope I hae helped a bit.
