Carolyn: maybe this will give you some good ideas:
Can you post a photo?
Carolyn....Just a fresh coat of paint can make a big difference along with different curtains and bedspread.
I agree with Tinyshoes, a fresh coat of paint and new accessories for the room. You may even want to make a theme for yout room...coastal, rustic, barnyard...
A new bed in a bag set can also give you a new look... https://www.brylanehome.com/b/bedding-and-bath/bedding/comforters-and-sets/ Bed Bath & Beyond is also a good resource.
For small rooms I like Apartment Therapy for ideas... https://www.apartmenttherapy.com/smart-decorating-ideas-for-small-bedrooms-241061 I usually stick to monochromatic shades of the same color in pastels when deocrating a small room.
