Actually, you should probably focus on names that don't have anything to do with your real name because you just never know what pervert will try and get your trust.
But then, your name Bionda is not going to easy to guess either. I've never heard of that name.

I don't know, good luck finding a sweet cute name.
You should ask if your mom or maybe your dad can come up with something. You're 11, so you're still cute, sweet, and adorable, especially to your dad, so he or your mom might be able to come up with better cute and sweet names than we could think of.
