Um Well I moved outta home 1 month after my 15th birthday I've only rencently come to reside back at my mothers.

Living outta home could possible kill you but you get use to eating less and walking more. I survied quite well on 160 $ a week ( although I'm in australia ) I had to pay rent, public transport to get work, food and I had 2 cats as well I had too look after by the end of that list I still had 10 $ left over each week which I saved. so basicly it just matters if your determined enough to let go of all luxury. Always hunt down the cheapest thing possibl I guess.

But I never regreted moving out it's just what I needed I love inderpendts. So I guess if your willing to give up things ( like the internet ) you shouldn't have much of a problem just much sure you always earn more than you spend and save the rest for a rainy day.
It will effect your furture think stressing that you think long and hard about the money thou.
