I hope your dad comes through for you, but again, I know you have been dissapointed many times in the past. Make sure whatever you plan is something you can handle by yourself. If you don't count on someone else, then you can't be dissapointed by them. Unfortunately life has taught me to be very greatful when other people come through for me- and to expect it when they are unable to. Not because they dont mean it, but because this is real life and stuff happens, they must take care of their own responsibilities first, and helping is not something they will always be able to do.
Look for a studio apt. If this is the first time you've ever been out on your own you don't need much space- a bed, a dresser and two tanks. Don't get house poor. In NY I know people making 65k a year living in studio apartments- if one of them heard you talking about a two bedroom they would have a fit. If home is so bad, a studio will be perfect- if you need a two bedroom for it to be an improvement, then it aint that bad where you are now.
