This is really very deep and meaningful and it has a message that is profound: don't shut others out emotionally because of your own insecurity..It has been said we cannot truly love another human being until we have learned to love ourself and I tend to believe that is true.
Often, especially when we have faced abuse ( in whatever kind of way) we are scared to let someone in..I don't know if this is the case with you, but would not be surprised if it was so.

On the technical side: I would have made the whole poem non- rhyming and not just partly, but that is just my opinion:)

Good job on portraying your feelings:)

God bless.
