I can't get use to my new bedroom?

We moved around a lot as a kid, and I've had tons of different types of rooms. Some I shared with my younger sister, others I didn't. The key to making it feel like YOUR room is to decorate and personalize it. Find something that comforts you, whether its posters, pictures, pottery, wall decals, etc. Start decorating. You shouldn't need much time to get used to it. Take it as a chance to start fresh and do some organization. :)
