Things You'll Need
Sleeping bag, blankets, or sufficient layers of clothing
Mat or cardboard to sleep on (optional)
Money (including change for laundromat)
Bottle of water (keep the bottle)
Small handbag (optional)
Good trainers or boots
"Travel" sewing kit
Changes of underwear
Toothbrush and toothpaste
Washcloth and/or soap
Small flashlight (and extra batteries)
Extra food (that doesn't need to be cooked)
Can opener (for canned foods)
Small weapon, such as a knife/pepper spray (guns are not recommended)
Credit/debit card (for emergencies only!)
Two changes of clothes
Coat or jacket
If you don't plan on going back, dye your hair in a handicapped or private bathroom (not the kind with stalls, but only one room) and cut it also. Wear clothes different than the ones you left in so your parents can not identify you. (You can leave wearing really simple clothes to not arouse suspicions, and change into the better, conservative clothes.)
Don't carry a picture of your family; you're likely to get upset and go back home.
Visit a church, mission, or public library for warmth, or an internet cafe for the internet. You could update the hardships of street life on a blog to pass the time.
Research runaway shelters in your state and neighboring states.
Do not bring friends along with you. They can slow you down and make it easier for the cops to track you. Plus, it's harder feeding two.
Try talking to difficult parents, telling a social worker or trusted parents about abusive parents, and releasing any stress your family members have imposed on you before you ever even think seriously about this.
Figure out where you are going to go and do some research: look for cheap areas, homeless-teen shelters, etc. But realize that any legitimate shelter will ask why you are not at home, etc. Your story needs to seem real and desperate.
Newspapers are one of the warmest insulating materials available, take advantage of this cheap material and stuff your sleeping bag and clothes with them; and if you're living in a field or urban area, you might burn them later if you have a lighter/matches.
Debit or credit cards should be brought, but only just in case. Take one that won't be noticed as missing, and use it only in absolute emergencies (if you run out of cash and there are not other options). Then get far away because it can be tracked fast and easily. Never use it on transportation or for a place to stay because it can tell authorities where you are going, even in taxis. For transport, buy tickets or pay with cash.
Always think of a better solution than running away. You may just need to talk to your birth/foster parents, if they are not too out of control, dangerous, drinking and using drugs. Remember, always be smart!
Ladies, you may want to at least shave your legs. Shaving with a razor in a public restroom could take way too long. Bring some Nair or Veet or something similar. Most of them only take a few minutes to get the job done and they're a lot easier than razors in the long run.
