The three names that have been chosen which are more like three versions of herself.

This is the name that she has chosen for herself, There is also a "is" instead of a "was" but someone else already said that.

It seems to me that each name was chosen with certain people's interests in mind, Christanbelle is a safe name for other people so that that feel comfortable and don't discriminate. Yoshie is for her family which as she says "made me acceptable to them". The last name is given to herself with her own interests in mind, connecting her back to where she came from which is both a blessing and a burden on her.

I think that this means that her own chosen name in both a blessing and a burden, A blessing in that she chose it herself and it represents who she really is but a burden in that she is now open to more discrimination than before.

"a safe name" could mean that the name was used to protect her for discrimination, A name that they see as is safe to use in their eyes.
