I first moved out of my Fathers house at sixteen. I shared a place with my ex. for 3 1/2 years. I was not at all bothered by leaving my parents house.
I worked my fingers to the bone for what seemed like nothing but it was something I was proud of. Eventually all my savings was lost when my job went through some 'downsizing' and my ex. also laid claim to most of my funds, which is another story entirely. Because of those problems, I ended up moving back in the with my Father, who was not very pleased.I then moved out again as soon as I could, because my relationship with my Father when I live with him, is not the best.
I eventually got married, and we bought a house together. ^_^
It's hard, and it can be a very difficult transition, but it's entirely worth it to have your independence. To have something of your own. Living on your own, and taking care of yourself is an accomplishment as far as I am concerned. You'll be fine as long as you plan everything ahead. Planning is very important to this process. Also, be responsible with your money. Don't piddle it away and then wonder why you don't have the months rent. When some people first leave their parents house, they buy buy buy because they get pretty excited and want to decorate and have their own stuff.
Make the money stretch, and save, save, save, save, save, save. And also, save, save, save, save, save.
Look through the pennysaver,(or your areas equivalent), for old furniture in good condition. Go to thrift stores, for dented but usable furniture or appliances. You can also get things for free, if you look hard enough. Garage sales, etc. We were able to get some furniture for free, from friends who were re-decorating and didn't know what to do with it. (Also, have a house or apartment-warming. PEOPLE BRING GIFTS! Food,appliances, dishes, etc.Or they are supposed to.)
You'll probably become a penny-pinching scrooge for awhile, but, it helps.lol
(Also, cooking is easy. If you can follow a recipe, you can cook. Think of it like a strategy guide. Just don't try to make complicated dishes right away. Start small scrambled eggs, spaghetti, baked chicken, stir-fry, etc. Eventually you'll get better, and you'll feel more comfortable making more 'complicated' dishes =D)
