My lower jaw is too short. Is it suitable for me to get braces? (Photo)

3 years ago, I had a dental check with a dentist. She told me that my lower is too short if I put the braces on, she is worried about all my upper teeth will be pushed forward and make my look even worse. But now I really want to get braces, i can't even close my mouth naturally, i want to have a great teeth!! Is it suitable for me to get the braces in this case? Thanks
